$1000.00 for s suspension means a full coil-over system. Or this could be a springs and shocks combination.
To lower a car, all you need is a lowering springs. but then again, your strut will need to be replaced sooner or later because OEM ones weren't designed to be compressed (lowering spings) all the time.
A combo of springs and shocks (gas shocks) can run between $600-$800 depending on the brand. If your budget is tight as this time, I suppose you can opt for a lowering springs first and then upgrade the shocks down the line.
