I am thinking building web application where buyers and sellers could meet and buy/sell items/service. (There wont be any item to sell butthey will pay for service )
But i dont know how to get commission like (http://www.freelancer.co.uk) but i am not sure about there will be bidding or not but the question is hot to get commision
Should i have my own account and get money buyer and send to seller when service is done?
Is there any detailed architecture / work flow / article etc. about this kind of process?
Does paypal or any other payment gateways support this kind of features?
