Do it yourself. I take it you plan on going off road and that's why you are lifting it? It is better to know how it all works and fits together if you have to do a trail repair.
If you need a new tool, buy it. Justify the cost from the amount you saved not paying someone to do the lift. This can include spiffy new floor jacks, jack stands and cut off wheels.
It's a dirty, greasy, get crap in your eyes and skin your knuckles, smelly, tiring job and you will most likely hit your head on something too. But it is worth it knowing you did it yourself.
Spray PB blaster on everything ahead of time. The 'capture' nut on the driver side rear spring will sometimes break loose. If it does you will have to at least move the gas tank out of the way to get to the nut. With the tank moved over some I was able to get a wrench up in there and used the frame to hold it in place. Do this spring first and everything else will seem easy.
Just cut the old u-bolts. You can't reused them and they are a pain to take off.
Make sure to figure out front/rear springs before you start and also which direction. Mark them as such.
