I do have one. A quick google search for amc 304 water pump pulley shows a couple out there for around $35. Or you can do all new like I did, but it ain't cheap!

I would think around $100-$150 if you're talking about a wrangler, maybe a little more if your talking the grand Cherokee with all the bells and whistles. You just said 4 door jeep, so hard to say.
