Robert,

Thanks for ASKing for a piece of multi-million dollar pies.

You Can have a piece of such pies...

By being
a

Finder

or

Broker.

If you've got Jim Straw's Finding work. I can't see any reason you could not find buyers for domain names which are for sale at any number of Domain Name Selling sites.

No need to start your own site. Find buyers for the sites already listed.
