Two sites I recommend you visit whether you’re on the buy-side or the sell-side are Guru.com and Elance.com. They’ve both been operating for years and have enough critical mass (i.e. a lot of people buying and selling) to make it worthwhile to join. If you’ve been looking for extra income without the hassle of a “job” then visit these sites and explore the various types of skill sets that are marketable by the hour on these sites. Everything from administrative assistance, typing, or writing to strategic consulting, business plan writing, and telemarketing is being sought and offered.

Finally, if you do decide to register as a provider of a service don’t try to be everything to everyone. Stake out a specialty and focus on establishing yourself in that niche. If the businesses looking for skills wanted a generalist they’d create one of the “jobs” to fill their need. There’s a good post on Elance worth reading on this topic: ‘Developing Skills Pays Off‘.
