If I where you, I would just get a stock 1911 off the shelf, like a Colt MK IV or even a series 80 - with nothing done to it. If you had some extra cash, get a partial custom, like a "combat elite" or something.
Just worry about shooting it for a while. Once you have 600-800 rounds through it, you can start determining what you want done to it.
You can "build" as nice a custom gun as a Baer or something, just doing it over time. Now it may cost a bit more (or a lot) over the long run, but there is less initial expense. the Baer is a big purchase for anyone but a serious shooter.
get a gold cup, shoot it. Get it dehorned, tefloned, trigger job, maybe some checkering, sights. then build from there with what you need, and nothing you dont.
You'll save money, paying it all up front, but you dont need to. there are tons of good small time gunsmiths, the trick is finding one who may not be the best, but does not fuck your gun up.
I would be very careful about taking any advice from gun forums, including gun broker, 1911 forum, etc unless you can absolutely verify who is giving it. Everyone is a expert on the internet.
Everytime I visit the range I am shocked at the dip shits there, and hearing them give each other advice is comical.
