Huge Wholesaling Companies

[J Woodfin]

I'm trying to grow my buyers list. I've been attending auctions and passing out cards that point investors directly to my buyers sign up page. A few were very receptive and took the card. But I noticed a TON of those who were bidding wouldn't even take a card, citing "their company" won't do business with me, or "they work for a huge wholesaling company".

Question:
How in the world can 1 person compete with conglomerates that literally have agents at every auction, cold calling every possible listing, etc.?

Who are these companies? Seems like they will buy anything. The margins are miniscule at best...I just don't see where small wholesalers fit in...
