People on the forums work on wide range of prices - but as with life in general, you generally get what you pay for - Although you will find some very good designers and coders who will work for what I would say is a "cheap" price, and could probably charge a lot more.

I think you may actually find a lot of people on these forums, use it to find designers and coders to work as third party for their clients. I think most people on the forums would be happy to do subcontract work - if they get the money coming in I'm sure they are not to concerned where it comes from.
