Get yourself "a guy", or do the installation yourself.
As others have said, the DIY is super simple. You'll learn something out of it too.
I personally wouldn't get the kit with H&R race springs. I haven't used them personally - but people who have experience with many suspension setups, and value their ride comfort have been overall dissapointed with them (or so I've heard). If you do end up getting them - let us know how they feel!
