And where can it be done? Would a place like Midas do a suspension system like this? Cost of labor? How hard would it be to do yourself if you have garage jacks, stands, and a compression tool? What‘s the risk of the wheels being misaligned? Sorry for all the questions haha.
I installed coilovers and a front upper strut bar on my car. It took me almost all day but I did it and I can't imagine how much I saved just by doing it myself. The only other tool you may need in addition to what you listed is a spring compressor which you can rent for a few bucks; I didn't have an air compressor available at the time either. I don't recall having alignment problems but I did take my car in just in case.
I've seen and helped people do it themselves, and it's not too hard, and the alignment shouldn't be affected. You may be better off to have a shop do it if you have no experience with such things. It will be pricey, but it will be worth it.
