95237 Freelancers marketplace mod

I have a freelancer site, similar to Scriptlance, which is "powered" by Radlance, and need to enhance it with the option for webmasters to accept and pay more than one winning bidders (programmers) for the same project. If you know how Radlance works and can provide a bug free mod please respond accordingly. I'm open to all fair suggestions/offers which can be delivered in a short period of time. Thank you.
