That's a line every consultancy that ever had to compete with another consultancy has told at least one client. But the truth is, for the overwhelming majority of application software, and particularly for any software that would procure a pentest through a market like this, the Bishop Fox "F-Team" is perfectly up to the task and far more reliable than a talented rando.

The software pentesters with gold-plated resumes do high-value targets (because there are more high-value targets than there are pentesters to service them). Google is not going to source Google Mail pentesters on DICE. Adobe doesn't source pentesters for Reader on DICE. Microsoft doesn't source pentesters for SCHANNEL.DLL on DICE. Apple doesn't source pentesters for the iPhone bootloader on DICE. That's where the A-Team ends up.

What transparency are you adding here?

If the argument behind this was, "we're going to drive down the price of pentesting", that would be a coherent pitch, although I'd still want to hear how you expect this service will do that; again, the market is supply-constrained.
