I have experience with being on a few micro job sites. I offer different gigs and/or listings on each one. I'm in:
Fiverr - I offer a variety of gigs ranging from selling traffic, to 100-300 word posts, to doing fun 3 minute foot clips, etc. (under a different username)
WorkWizards - I do a range of services independently for them directly. I create articles, videos, simple banners, etc.
SEOClerks - I offer all my writing services there, including article writing, reviews/blog posts, and stories ranging from customized storybooks to customized fetish stories. I offer recommended tumblr posts and twitter listings, and yahoo backlinks.
They have all kept me busy, and I hope to continue to get more clients online
