Most shops range by the hour or the job. I'm sure someone will chime in and give you a heads up on a near by shop.
FWIW, you will need a bit more then just the pump (copper crush washers for the banjo bolts, up pipe to turbo gaskets, coolant if the ab comes off...Etc). It's a full day job at minimum. 2-3 hrs at most to pull the cab. 1-2 for removing turbos, fuel coolers and pump and probably installing new pump. Another 1-2hrs getting everything back on and what not. 2-3 hours to put the cab back down and top off fluids.
I don't know how much they charge out there, but in Cali it's $90-120 an hour for shop time minus parts. I guess you can say about 1k for labor at most, don't quote on that though.
