Anyone have any leads/contacts for individuals/groups that would provide non 7A acquisition financing?

I have a business under LOI, ~$2M EBITDA services businesses and need a small amount of acquisition financing to help bridge the gap on the acquisition. Seller is financing a portion and we're putting in a few million in equity, but looking for $1.5-2M or so in additional capital to get the deal done.

Would appreciate any intros/connections if folks have them.

Thanks!
