here's my suggestion... don't waste ur money. and save some of it for the electric bills that will roll in. stay away from LED's. Stay away from buying hydroponic setup 'pre-fab'. i've seen ebb and flow systems with like 12 buckets, a rez bucket, and pump and a timer sell for like 400-600 dollars - which is completely retarded when you could DIY the same setup for less than 100 dollars EASILY. I've seen aerocloner systems for 400-600 dollars when you could DIY one for about 50 dollars. Shop at HTG.com and you'll get a decent price for lights. For anything else, find a reputable dealer with good feedback and at least a 30 day return warranty on EBay. (Though i also like their GrowBright vortex-like inline fans... they are only 3 dB higher than the Vortex... and i use insulated ducting so i can hardly hear them at all.) I also picked up a ozone generator from them, just for convenience, though you can find one for 20 bucks less and with free shipping on EBay.
Buy things (large purchases) online. Locally (home depot or lowe's) you will pay a premium... and then pay tax on top of it. IE; a 70 qt de-humidifier at H.D. will run about $239+tax for about 260 bucks. I can get a different brand name that does the same thing on ebay for 160 dollars plus free shipping.
It sounds like you want to start a business. Your first responsibility as a business owner is justifying cost. IMO, some person are too eager to pay a premium for a brand name when the less expensive gear will do just as well. Also, you could have a much larger system if you keep price in mind while doing your shopping.
And stay away from tents. And stay away from 'roto-gardens'.
