how much do machine shops typically cost?

my engine is in the shop as we speak and I'm into him for about $1800. I also supplied all the parts Pistons,rods bearings everything!! He's going to line hone for crank bore out cylinder walls 30 over for my pistons and assemble the short block he also resized rods ect....hope that gives you and idea. I know he's not cheap but i know I'll have a strong motor! He has a great reputation!!
