I'd like to suggest doing repairs yourself, if this is an option.
I purchased my jeep from Collin Bros and they are indeed great guys.
However, repairs on vehicles can be easy.. You'd be amazed what you can do by taking a shot at it first, on minor repairs & upgrades. (uncle google and youtube are your best friends here)
Also, sometimes shops will "deal" with you if you purchase the parts on the cheap and take them to their shop and they sell you only labor to install. (I've done this with Goodyear on parts for a 4-Runner on a repair I couldn't do.) <-- this is rare, but some shops still do this.
I like hbgirl's advice, simply call them and leverage their own competition... Collin's Bro will fix for $x, can you, 4WP, do a better deal?
Finally, there's a lot of guys on this forum that will do back flips for a case of beer.
(after said repair, ofcourse!)
