The entry covers everything from announcing to the world that your available for hire, getting contract-work, pricing, and even talks about taxes. Here's a clip I really liked about pricing (a question I receive a great deal):
When you're just starting out, the tendency is to underprice yourself because you really want to score the contract and you're optimistic about the number of hours it'll take to complete. However, you'll forget to take into account things like taxes and time for administrative tasks. As you get more experience, you'll adjust your prices, learn how to read different types of clients and what their budget range will be, and have enough confidence to walk away from contracts that aren't worth taking. I'm much more likely to do interesting work for lower prices, but I'll only take on tedious stuff that's well-paid. When it's time to ask for the upper range, I use an unscientific method: I quote the highest rate I can while still keeping a straight face.
It's just food for thought if you're thinking of making a move and want to make it gradually. Thanks to Gina Trapani, the author of the article, for the great Lifehacker post.
