you are going to need 2 or 3 chambers
VEg and flower.
You may want ot look into a Sea of green method with that size room.
a 400 hps for flowering --
at least a 250 MH for veg, and soem floros for clojning.
youll need mylar, 50 ft of it to double up and flatten it , and ventilation. I would sugest a squirel fan and hme made carbon filter
youll also need internal fans for moving hte air around.
dotn forget the home depot trips for wood, nails, cahing etc...
and save at least 100 for quality seeds.
but without knowing more about your area --- stealth, indoor, you ahve air conditioning, central heat, etc its hard to say ---
