Plumber Recommendations please

Hello All,

My better half and I are moving into a new apartment that has no washing machine hook up (we had a hook up at our old place and bought an electric washer/dryer combo). We met with our new landlord last night and he said that we could bring our electric washer/dryer combo as long as we paid for the hook up to be installed. I am assuming we will need a plumber for this? Would anyone please have any recommendations? I would hate to go into this blind. Also, has anyone had a hook up installed before? Any idea on cost/difficulty?

Thanks, in advance, for your help!
