First off.. how much $ you have?
I would go with 600 bulbs as that way you can have two rows of 3' wide with area between to walk. 4 AC 600 hoods total, 6 if you really want to blast them with light.
6 plants trained through SCROG screen.
50' of panda film $35
two dual 600 digital ballasts = $500
four AC hoods with ducting = $600
three 6" fans.. one for ducting, one for cooling inlet, one for cooling outlet = $300
temperate controller for cooling fans $80
8 bulb HO t5 for clones and early veg $200
two 16" oscillating fans $60
Wiring for 240 circuit for ballast and timers $150
Scrog Screen materials $70
So your in the neighborhood of 2K. If you don't have any grow supplies... PH, PPM meters, measuring cups, containers, scissors, nutes, cleaners, add another $500
