You don't get how these things things work.
An RFQ (request for quote) by its very nature is a request for specific commodities from an existing purchase contract, which are evaluated on a cost basis.
In it's simplest form related to IT, a server vendor has an part number for a hard drive listed on the GSA contract. Multiple resellers are able to sell that part. A RFQ is a solicitation that says "We would like to purchase 50 units of part #12345". The reseller with the lowest price wins.
