Welcome John,
If you've narrowed the search down to a few guys (all of whom you mentioned BTW are excellent choices), I'd give you one piece of advice - pick the one you think will do a piece that best complements
YOU, and get him started. Give him all the time he needs, and don't worry about financing the whole project now, and making every last minute decision on details of construction. You'll have plenty of time to arrange the finances and iron out details while your gun is patiently awaiting it's trip to the bench.
I talk to a lot of people who are concerned with proximity to the smith, getting their funds together, and the time factors involved before even starting a project. Fedex, AT&T, and the internet have made our world a small, friendly place. Don't worry about the money at the front end - Nobody who's doing a good job these days will be calling you in two weeks saying "Surprise - You're done! Now send money!" If you need to make a change, just give plenty of notice - we want to make sure the finished product is just what you wanted.
I learned these lessons in dealing with the nice folks at Westley Richards. ( I know, How lame that I can't build my own doubles

)They're not close, they don't have the time for a lot of communication, and they're not particularly fast. But when delivery day rolls around, the wait, the price, and all the anxiety disappears.
