I'd just like to add that I promise you will be displeased with the results if you go out and buy a ~$1000 gun and slap in a drop in trigger and hammer.
"drop in" parts on 1911s of any flavor are a very sloppy "fit", and most are undersized for the application. I don't know how many times I've had someone come to me showing me their brand new XXXX 1911 that they "upgraded" with some new parts but it just doesn't work right. Drop in triggers slop around in the frame. Drop in hammers don't interact with the stock disconnector and sear consistently or predictably. Drop in grip safeties leave gaps at the frame tangs that can pinch the web of your hand.
In my personal experience, double stack 1911s have feed issues unless you find a combination of ammo and mags that your gun likes. It helps if you reload.
That said, from what you've said you want, you're looking for a full house custom gun for the cost of the parts... There's a lot of work that goes into getting such a mutated beast
evil
to run properly, and drop in upgrades can cause all kinds of trouble. If you DO get something with plans to upgrade it, don't do it yourself unless you for sure know what you're doing.
1911tuner on here is the guy you want to talk to, but I still SERIOUSLY doubt you're going to find exactly what you want in a production gun, especially for around or under $1k
