2 quick notes. The grows would be fairly large. If you are doing it legal the power usage and smell shouldn't be much of an issue.
2600 sq. ft. would grow a lot of plants/ You're going to want to partion it off so you have atleast 2 sealed rooms. 1 for veg and 1 for flower.
I would go with 600w hps lights,they're more efficient and produce less heat than the 1000's. Power consumption is going to vary, but generally about $20 a month per 600w light. So if you're going to flower in say a 400 sq. ft area you're going to be looking at about 300 plants yeilding anywhere from 1 oz.each to maybe 4oz's max for about 5 foot plants. You would need about 12 600w lights in that room alone. You could get some lightmovers and cut that in half. With 12 600w lights you'd probably be spending $240 a month in electricity for those lights alone, plus your veg room system and plus whatever climate control system you need.
