Im not sure how much the shops are around you are, but I paid 450 for my body lift. Thats por parts and install, but I had also called other shops prior and they had told me as high as 800 because nobody caries a specific ST body lift for years other than 00-01. As for a tt/sl you should be able to do that yourself depending on your skills. if not, I couldnt imagine a shop charging anymore than about 100 bucks for the labor (probobly 2 hours labor)
When I did my lift, I did the body lift, shackle lift, torsion twist, and axle flip. after it was all said and done between parts and labor the lift cost me about 1400 dollars. Then my wheels and tires ran me about 800 dollars for 35/12.5/15's and 15 inch wheels (but I got cost, usually about 1250).
Depending how big you end up wanting to go, you can stay around 2000 safely. Just do alot of research at the shops in your area and see what they say.
