Plumber/Water Heater Repair recommendations?

[Lucas Hammer]

So I have a 2-flat in Little Village near Cermak and California and the water heater in one of the units has a small leak from the intake pipe. The pilot light has gone out twice in the last week and I think that it's due to the water running down the tank. Anyone have any recommendations for a trustworthy plumber that does the job right and won't cost me an arm and a leg to check it out?
