10k Eh, not a bad way to start
.... This would be what I'd do...
First off, tear out any carpeting, cover any openings in the walls, get rid of our cover any windows. Then clean the room thoroughly.
Once your room is completely specless and and closed off. Paint your walls white. All white, you could even use a special type of gloss paint that leaves a somewhat "shine" which would not normally be used for walls. Also, you could line your entire room with mylar for the most reflectivity. If you have a concrete floor, paint it white.
Once you have your room finished, get your ventilation in. Go to a hardware store preferably "Home Depot" or "Lowes". Get the foiled tubing thats from 6" - 1' in diamater. Place the tubing aroung the top of your room, and you could also place holes in the sides of the tubing to pickup air from all around the room. Then put the tubing into your air duct or out a window. I recommend using the air duct because no one could see the hole in your window. Make it suck through there, and put a large garage fan in the corner of the room where your ventilation doesn't pickup from.
Then, buy three or four 3'-4' long HPS/MH ballasts. You should also get auto-misters on the outskirts of the room.
Build wooden stands to hold your pots in, and have a nice drainage under them. Figure out the rest i Gotta go...payce GL! 10 g's mofucka!
