This is rifle is the first time I've used a custom action - and for design reasons I moved towards the shilen. 1. I wanted a BDL format and the ability to have a repeater when hunting. This meant that if I used a Savage or Rem700 action I would have to have a smith open up the mag box and mess with the bolt release. This was not a problem with the shile at 3.950" for mag opening and side bolt release. 2. I have used Shilen barrels before and like them. The also make their own trigger, which I opted for based on reputation alone. 3. If I went all 'Shilen' then they could deliver a barrel action to my specs. All told the cost was right at $1600. Steep, but not crazy.
This left me a stock to buy (easy with Rem700 clone) on ebay, internal mag box from Wyatt, follower and spring, and bottom metal and screws. Finally, I needed a base to fit the Shilen action, which they sell. (Rem700 base doesn't fit.). I haven't added everything up, but probably no more than $2200 for a pretty near custom rifle
. Custom includes throating chamber to dummies I sent Shilen.
So the question becomes, if you want to use a donor rem700 and not change out stock and trigger, then you will easily come in under $2200, but if you upgrade to a jewell trigger and an equivalent HS precision stock, then ... If you want a repeater that can handle over 3.6+" (I'm not sure what the max is for rem700), then you will be close to the $2000 mark.

This is a group buy over at SnipersHide. The smith, Chad Dixon, has set up his shop to run high throughput CNC Rem700 truing and barrel fitting. The prices look insanely good. I have never worked with him, but am considering sending my one and only Rem700 for this service.
Sorry about the long email, but I am just trying to give you some insight into my thought process incase is helps.
