Wholesaling a Multimillion Dollar Portfolio Deal

[Langston Grant]

Hello, my name is Langston. I started wholesaling in May of 2022 and this is my first BiggerPockets post asking for pointers. 
I have an amazing opportunity to make a good chunk of change on a 20 property bulk sale in a certain city.
The seller is asking for $8.9M. I’ve run numbers and they come in for me at around $7.3M.
Either way I’m confident I can find common ground on the price, however, my question is: where the heck can I find someone/some entity with enough capitol for a $7-8M all cash real estate deal? I’m sure it’s possible.
I got a tip that I should call around and find a CCIM guy or gal who’s in contact with investors like that. I have spoken to a couple of them who say they know investors who invest in the same area that these properties are located. So I am excited. However, I don’t want to put all of my hopes in one basket with these two CCIMs and their contacts.
I am asking for any solid advice on how to find a cash buyer for this type of deal. Should I get in contact with representatives of Hedge Funds or Commercial Banks perhaps? And how should I go about doing that? Anything helps. I appreciate you all in advance. Thank you!

@Langston Grant it's way easier for someone to just broker the deal (i.e. a commercial broker bringing a buyer, and asking seller to pay the fee, or for buyer to pay the fee), so see if one of the CCIM's can pay you some type of referral fee/consulting fee.
