If you buy Kimber 4tc unterminated bulk for your speakers you'll be within your budget. You can also research bulk VanDenHul wire. They go $7/foot. $70 will get you where you need to be with cables. Speaker cable is the only thing you realy need
That's what I do for my system that is closer to $7000.
