We are looking to possibly convert our 26 velocity sterndrive to a twin OB setup. Does anyone know somebody who has done this? Just looking to see what it might cost for the rigging and transom conversion. Also if anyone knows of someplace who might do the conversion... We live in NY so obviously the further north, the better. Thanks!

Don't do that.
Filling the transom, adding a bracket, and rerigging with twin OBs is going to cost more than the boat is worth.
Sell the boat and buy a twin outboard if that's what you want.

Man! A friend of mine had a 26 with 2x 300 pro max,s on it what a freaking blast!!! 0 to 85 mph now.

i saw one with two outboards on it this weekend, looked killer. couldnt see inside but i imagine the cockpit was alot bigger without the inboard
