Are you talking just the turbo.. if you do it yourself the kits are usually 100-120... To have a shop do one id have to guess like 200. I just rebuilt a turbo for myself and it was easy, just if you wanted to know.
about 200-250. rebuilding it yourself may be hectic but if your going to do it, then make sure you get everything spotlessly clean before you put it together. Any sand or grit in the bearings will spell death for that turbo. and done bend the turbine fins whatever you do.
