If you have good writing (or other) skills, you might wish to check out The Complete Idiot's Guide to Elance by Karen Lacey.
Elance is a website where clients come to pay creative people for their skills. Jobs are posted looking for logo design, articles, web pages, and hundreds of other possibilities.
As in other Complete Idiot's Guides, nothing is assumed. Each detail is explained, from signing up with the website to posting a proposal, submitting the finished project, and how you get paid. Every clickable button is described and you find out how and when to click it.
This book will be in the New Book section for another month. Come and check it out. Maybe you can put a few extra dollars into your bank account.
