Cjford said "Interesting I thought this would be one instance it would be very easy for a quote. More or less drilling a hole thru side of house adding a shutoff valve and tying into an existing water line? Would do the job myself but it's more of a time issue for me not so much lack of being capable. "
If you want ballpark for a plumber , parts will probably be around $70-$100 dollars and at least an hour labour so I would guess it would cost total $200 maybe? But call a plumber and they will give you a better idea.
