Hi,

I have a project of an online website in which i would be collecting monney from costumers for companies who would provide their services.
A little bit like hostelworld (http://www.hostelworld.com) that takes a commission on the top of the invoice.
In my case, the supplier who's receiving the monney through my website would pay me a commission.

An idea of what name this transaction is called and any named of company that would propose this service?? (can't find any provider)

PS : sorry if my english is not perfect, i am french.
