I bet you can find someone to help you on
http://www.scriptlance.com/ or
http://guru.com/
Find freelancers at the world's largest online service marketplace. You just post what your looking for with your budget and people bid on the project. For payment I think you use an escrow type service and I suggest you ask for a demo before making payment.
What I like about these sites is that many of the programmers are from oversees and will work cheap.
