I mean, he wants to fit bigger tires. It doesn't sound like he wants any type of performance lift, doesn't want any trouble (read TIB camber issues) and wants something relatively cheap. I'm not the biggest fan of body lifts, but looking at his constraints and criteria, a body lift would be good.
OP: If you go the body lift route, expect to pay around $250 for the lift, then extra for bumper brackets, gap guards (so you can't see the space between the bottom of the bed and the frame), shifter extender, and steering extender. Then, you'll be able to fit larger tires, which will cost more than smaller tires, and will take re-gearing (expect $400-600 to have a shop do this).
It'll be expensive. Your best bet would be coil spacers up front, alignment, and a size or two larger (than what you have now) tires.
