Similar to running an e-commerce store of your own, you'll be your own best salesperson. How you describe your products and present them in pictures will be the only way potential buyers will know what they're buying. So take time to write your product descriptions to make them sound exciting, without promising something that isn't true. For example, “Exciting Batman comic book collection” doesn't sound as appealing as “Dive into adventure with one of the greatest heroes of all time! This unique collection of Batman comics promises hours of adventure….” Okay, so maybe that was a little cheesy, but you get the idea.
There are many pros and cons to freelancing. On the plus side, you get to make your own hours, set your own rate, and work on a wide variety of projects to keep life interesting. The downside, however, is that you're not receiving a steady paycheck (clients may not be that reliable when paying their bills on time), you always have to seek out your next job, and you don't receive any benefits. But for many people, the good outweighs the bad, and freelancing provides the best balance between income and freedom. While this might not be the sexiest way of making money online, and it definitely requires a good amount of actual labor on your end, the Web can be a great resource for launching freelance services or building a reliable, ongoing career for yourself.
