I know this is a tedious question, but what do you plan to keep?
The reality is that the required outcomes in terms of environmental parameters do not change based on aquarium size... they just become more difficult to achieve.
If you want to do an inshore patch reef with mostly softies, Euphillia, etc, you can probably get away with natural lighting, x10 flow, no surge and maybe $20 per gallon.
If you want the whole thing to be reef crest acropora, you will need suplimental lighting (I would guess 50 x 1000W) and 20x flow with surge... I don't think that this is a practical option, but if you want to take this path, allow $50 per gallon ($500K project).
Probably the best option for this setup would be an 8 foot diameter patch reef over a sand environment. You could spot-light the patch reef with supplemental lighting and provide localised surge, while keeping the over-all flow modest. This would create a unique environment most of us have trouble duplicating... rays and garden eels would be very cool. You could bring in this project at $150k - $250k.
