A plugin for online RFQ – From requests to bids

Hello everyone,

I have set up a website with DJs and Bands. I want potential costumers to be able to make a general request, for instance “A privat party in London with the need for jazz-music”, and then the artists would be able to bid on this request online. A normal form of RFQ system, from costumers to vendors.

Anyone know of a plugin for this – or alternatively another software system?

Thank you very much!
