eProcurement Plugin - Wordpress

Hi,

I am looking for a plugin for eProcurement (Online Bidding) -
Supplier Registration and Approval by Admin (Custom fields)
Create Bids (Requests for Quotation and Tenders for registered Suppliers) - By admin
Suppliers be able to respond to bids(Requests for quotation and Tenders) - Registered Suppliers
Evaluation of submitted Request for quotation or Tenders - Admin

Sounds like a custom work - you may not find it as “out-of-box” solution as template.
