probably two 1000w lamps for flowering and a 400w mh for veg, one big fan and one smaller one, you'll also need all kinds of stuff like medium, seeds or cuttings, mylar etc....you should be able to stay under 2500$ for everything except electricity, time invested (which will be loads!) and incidentals.
Even with all this stuff it could be hard to pull off that kind of harvest until you've gotten the hang of it unless you're really good.
