$300-$1000. If you find a local guy for the install, it could be around $200 plus as low as $60 for the four wheel alignment. There's a shop down the road from me that does them for $60 every Friday. Gets busy and you have to wait a while if you go later in the day, but it's a good price. If you go to a shop for everything, expect $100-$125 per labor hour and for the job to be booked at 4 hours, plus cost of alignment which I've been quoted up to $200.
