First of all.
Now, if you have 1 day to put aside, you could do them yourself. Without springs it should be just a few hrs at most.
I did mine with springs and I will NOT be doing that again
As for local??? Nobody except myself I trust to work on my car. We have sponsors here that could do it for you.
Sansone ford has a free pickup/delivery if you cannot make it out to jersey, excellent shop!.
Mustang Magic is right in long island if you can make it out there.
If you do not see these options as plausible, give me a shout, I will hook you up.
