oh, well if 1500 is your budget for just the suspension components, then thats reasonable. that should get you the front coils/shocks, rear shocks, dakars and new uca's. if you want to trim that cost some you could get an AAL in the back instead.
but ya, this is not a small, cheap mod your looking at doing here sir, its alot of $ and work. worth it once your done, but it can be a long road.
