I need springs, helppp

I was looking at my car today, and I was disgusted by the stock SUV look.

I'm saving up some money and want to buy springs, I've read about H&R, Steeda, and Eibach springs. Which would be the best for a nice drop and a nice ride? Prices would also be nice.

Also, I don't know if I will be able to install them myself, how much would it usually cost? Is it hard to install?

Thanks
