Smaller water pump pulley

The radiator is new. It's an aluminum 2 row. I don't see a brand or any markings on it. The fan sits flush with the shroud, and it's about 2 1/4" from the radiator. Any suggestions on a good 7 blade fan that won't break the bank?
I found an original Mopar 7 blade on this site. Place a wanted ad in the classifieds
