First, contact ARC and see if you can actually do this.
Second, since I assume this is an outside load bearing wall, you may need specific engineer approved drawings, a call to the county building department should clarify specific code requirements will need to be met.
Since this is a major project, I would stick with name companies, I have seen 2 projects that neighbors had done by T&D, and both appear to have been done very well.

Good luck, and I hope this helps. I cannot stress enough to do your homework (1 and 2 ) above before contacting any builder.
