it's not that tough of a job. any weekend wrench can do it. i'm around for support too. i've helped quite a few guys via phone to install them.
in the past i have even had people come do it here. generally they stay overnight though, as it is a long day, and i won't wrench on a hot car.
by the way, install time is generally between 8 and 12 hours, depending on how much cleaning you do while you are in there
