Well then your stuck with 2.5-3". Going over 3" requires a-arm, which adds about $400 to price. That will put you over the grand mark, probably closer to $12-1300.
Easiest way to stay under a grand and get the most lift would basically be this setup:
Front:
(1) OME 927 springs (

(2) Bilstein front shocks (

(1) 1/4" spacer plate (

(2) Teraflex bump stops (

Rear:
(1) OME 731 springs (

(2) Bilstein rear shocks (

(2)Rear spring isolators (

(4)Hockey pucks to use as rear bumpstops
Basically the springs give 2.5" of lift, and anything you do to the front is doubled. So adding the 1/4" plate would give 1/2" of lift. That will give the front 3" of lift(and sit about 21" hub to fender). The rear is simply adding what you put in. Each spring isolator gets 1/2" of lift. My 3.5" kit runs 2 extra isolators per side and sits at 21.5". So if you only add 1 extra you'll sit at 21" and be level.
Now later down the road, say you save enough for the a-arms, you can buy those (~$400), and have potential to go higher. At that point you order 2 more rear spring isolators(add them to make a total of 2 extra per side) and then head to home depot or lowes and get (6) 2" conduit nuts. It'll cost you less than $10. That's your clevis lift, no need to spend almost $20 on JBA's. Anyways, 3 nuts per side will give a 3/8" lift and sit you right around 3.5" of lift. If you run OME springs, the largest clevis lift you would want to run is 3/8". If you want Ironman springs then run the 1/2" clevis(aka 4 conduit nuts per side).
I recommend doing it that way because it's easier to do a clevis lift than unbolting everything under the hood and dropping the spring assembly just to add the spacer plate.
