fyi, this is NOT a do it yourselfer. Top install is an art. You've got to stretch, pull, tighten, fasten. getting it all straight, tight and looking good is an art. I got mine done for around $500, but I took it to a family owned business that employees a lot of south of the border people. they did good work. on a budget, find a hole in the wall place like that, or go to mexico, but just a warning, as you can spend a lot of money and get crap if they don't know what they're doing.
