Is a realtor needed in a wholesale deal?

[Ruben Valladolid Jr]

Im a realtor, and I have a cash buyer (Up to about 850-900K) that is also a flipper. Not having any luck finding my buyer a flip on the MLS, so I was looking for alternative ways like reaching out to wholesalers.

Will I get cut out of the deal if my buyer goes with the wholesalers property? In other words, is there anyway I can represent my buyer and get a commission in a transaction with a wholesaler? 

Kind of new to all this, so i appreciate the patience and guidance.
