2-3 inch lift for 2006 Sport w/bad rear leafs

I'm sure their are many threads on this one however, I wanted to get some direct advice. I have a 2006 TRD Sport Quad Cab with a Topper. There was a TSB on the rearl leaf springs however, years back Toyota would not replace them because it was out of warranty. Now the springs are totally shot and its sagging in the rear. I am looking to replace the springs and add a few inches of lift. It's my everyday driver and I don't some minor offroading nothing intense. Not looking to drop thousands but I plan on keeping the truck for many years. Any advice on basic setups and websites would be appreciated. Thanks

 

Yep, 4X4

 

I was trying to stay around a $1000 or less but that may be out of the question.
