As someone who's been immersed in a number of online industries for quite some time, I know a thing or two about what it takes to succeed in this arena. However, just like you, I started at ground zero with little knowledge, but a great deal of passion. What I learned along the way were some invaluable lessons from failure that hurt at the time, but helped immensely in the grand scheme of things.
Advertising. You’ll need to get the word out about your sewing business, and one of the best places to start is with your friends and neighbors. Make sure they are all aware of your services and are willing to pass around your business cards. In addition, you should put up fliers in local fabric stores and get to know the employees so that if someone asks, they’ll be able to refer you. Any business needs a website, and yours will be no exception; you can put up a simple one that outlines what you do, and tells the reader what kinds of prices to expect. Finally, by joining organizations like the American Sewing Guild, you’ll be able to stay in touch with others who are doing the same thing as you.
Find a profitable niche. Starting with your interests, write down as many niche ideas as you can. Think about topics people might search online. Ideas include passions (like surfing or body building), fears (like spiders or speaking in front of crowds) and problems (like getting out of debt). Do keyword research to see it others are interested in the topic. Find out if a domain name is available that matches the keyword 100 percent. 
Your Deals. In addition to establishing a per-class price, also offer packages to entice people to sign up for more than one class. For example, if you intend to host classes on making soap, offer the classes individually, as well as in a group. Someone could take a class learning how to use fresh flowers in homemade soap, or they could buy a bundle that teaches them how to use those, fresh herbs, and plastic toys for kid’s soap. However you decide to price your classes, remember that the buyer will want to feel like they’re getting a lot for their money. If you can provide that in a fun atmosphere, they’ll likely be back time and time again – and they’ll bring friends.
Finances. You need to be good at quick math and be able to make quick decisions. You have to be careful how much you pay for a book, and then keep careful track of the expenses involved in selling it. For instance, when you sell on a website, they’ll take a commission from the sale. In addition, some sites, like eBay, will charge you a listing fee for each book. If you request that your money be deposited via PayPal, then you’ll be charged a transaction fee per book. If you’re not careful, the fees will quickly negate your profits.
Robert said he did an average of 4-6 of these gigs per year for a while depending on his schedule and the work involved. The best part is, he charged a flat rate that usually worked out to around $100 per hour. And remember, this was pay he was earning to advise people on the best ways to use social media tools like Facebook and Pinterest to grow their brands.
Tools. You don’t need much to work as a home-based freelance writer, but there are some tools that you must have. The most important will be your computer. Get the fastest Internet access that you can afford. It doesn’t matter what kind of computer you get. Just make sure you’re comfortable enough to spend a lot of time with it. Most clients will request that you submit your work as a Microsoft Word document, so make sure that whatever programs you use are compatible. In addition, because you’ll be spending so much time at the computer, make sure that you have a good work area with proper lighting. Some clients will want to be able to reach you by phone or Skype, so have both set up and accessible. You’ll need an invoicing program, such as Freshbooks, and a good bookkeeping system to keep track of sales, orders, and accounts receivables.
My next self-funded business hit $160,000 in revenue in its first year alone. After that first taste of self-made success, I’ve gone on to sign consulting contracts worth tens of thousands of dollars with startups like LinkedIn and Google, launch profitable online courses, and grow my blog to over 400,000 monthly readers and $50,000/mo in side income.
Display. Just as in any retail operation, the way you display your wares will greatly impact your sales. Produce should be placed underneath a cover to protect it from the sun, but be sure to allow at least seven feet of head room. Display your prices prominently, and clearly identify the things that make your product special. Personalize your stand with signs to inform your customers.
Find an audience for your passion or hobby and you’re all set to make money online doing something you love via a niche website. That of course, is easier said than done. Creating a profitable niche website takes time and is not intended for the faint of heart. But, if you can hurdle the steep challenges and positively answer a few key questions on whether the website business idea you’re thinking about is profitable, then you can begin building it and eventually monetize through advertising, affiliates, or other relevant products.
Take surveys. You can earn $50 to $100 per month in cash and products by taking online surveys. Find survey sites by searching for “paid survey sites” online. Sign up for several survey sites to increase your chances of being selected for higher-paying surveys. Register with an email address, and check your email often so you can respond quickly to survey offers.
Create a killer course experience: With your course validated and in the works, you need to figure out how people will take it. Most course creators choose to host their courses (after going down the path of learning how to make a website) on their own blogs. This way, they get all the value of bringing customers back to their site on a regular basis. I host my own courses from a subdomain on my own site so I can easily add more. The course experience is incredibly important as well. And after trying most of the solutions, I highly recommend Teachable—an online platform designed specifically for courses.
