Ok, final decision. Forget the white rims. Raw Mark V single speed prebuild (450) plus all black parts (25) plus extra cog for flip flop fix/free config (20) = 495, plus powder coat (50 - 60) = 545 - 555. Plus assembly and tune = about 600 bucks. Right at my budget, and everything I was looking for. Should be ordering within the next couple of days.
Here is a very rough, and poorly done mock-up of what it should look like final. just for reference.
