Handi-capped Borrower/Buyer Perks?

I’m putting together a deal to help a good friend expand his manufacturing business. He’s in a small, rented building that he has outgrown. Nothing exists in our market for him to buy, but there is appropriately-zoned land and local contractors who could put up the structure. My question is, are there any known resources to assist my friend in getting BETTER financing or even grants. His business is well established for multiple years, his credit is sound, etc. Also, he’ll be employing 4-12 people, if that helps. Any advice as to where to look would be much appreciated.
