Been looking for RTA bushes not long ago, they were between $140 - $170 from ebay to bursons. Workshops may get them cheaper.

Installation you're looking at ~$80 an hour (standard mechanics pricing), my guess around 2 hours maybe? it's not a hard job just that you need to take lots of things off before it can be pressed out. And wheel alignment ($50)

But again, every shop is different.
