Suspension lift or SL will net you more than just room. Its an increase in components usually if you don't cut corners and overall should be upgrades and upfitting compared to stock. A body lift, or BL will net you some room and some room for articulation but ideally its the tires and wheels that net you "lift". Sometimes people use a combination of both to achieve the results they're after.
Outside of that BL start around $160+ and anything that's a decent quality in SL starts around the $449+ price point. Best thing to do is to research some of the build threads on here, see what was done [and why], research the parts and brands, compare with your needs and budget and start there.
