I want to convert my basement shower into a Bathtub shower how Much will it cost?

I need to convert my basement shower into a bathtub shower. I can do all of the drywall and caulking and pretty much everything but the plumbing. How much would it cost to hire a plumber to mover the drain install the faucet and move the shower head to the opposite side of the wall which is only about 2-3 feet. I want to go cheap so I don't need anything fancy. Like I say I can do all of the work except the plumbing. Also how big of a job will it be for a plumber? How many hours should it take? Any help will be much appreciated.
