Holley Carb Wizards?

I am the owner of a Holley carb on a 1966 IH medium duty and it has defeated several of us in getting it to work right. It also has some casting issues. I am about to ship it off to a guy in NJ who does this for a living but he is 3 weeks out and I wondered if all of you know of anybody closer or faster.

Thanks.
