If you are having things installed, then no way are you going to get out less than a few thousand. But there are so many other things you should do in order to make the jeep handle the lift and tires. i.e. Sye, stronger axles, re-gearing. You will find that it can get pretty costly to do it right. I suggest do some searching on this site about fitting 35's before you start anything.
