Hydraulics ?

My car is in the shop this week and I have a 03 Impala rental. I have a compact that I'm putting air on as soon as it gets out the shop, but I'm loving the space in the Impala bc I have a wife and daughter. I want to know where's a good source of information on hydraulics and good shops in Florida. I'm seriously thinking about getting something that size and juicing it with accumulators. How much does a basic install usually cost? In the end I want something that will FBSS and a standing 3(I know that's not a basic install). And has anybody had any experience working on the suyspensions of the newer Impala? And If you have pics that would be great.
