Lots of the guys on this forum are replacing the crossmember themselves, Maybe you could do it yourself too.
If the Xmember is rusty, might look the car over for other rust...floors under seats, trunk floor, rear quarters behind wheels, etc. I've been told there is usually more rust than you first find. On my chally the roof had a little surface rust, then later found old bondo hiding a large rust thru area....had to replace the roof and drip rails which added to the cost I was not expecting.
