I have! Try mylot.com and microworkers.com. There's also ifreelance.com and paidpostingforum.com. They offer all sorts of posting jobs and if you kill a day at it, it can get you some serious money. I made $200 in a day and a half. That's roughly 4 days at my regular part-time job (yuck!)...hope that helps but if you're not talking about those types of sites I have a bunch more I think could help...those are the ones I've tried first.
