geothermal & plumbing supply and install.

Im aware of all the companies that supply heatpumps, underfloor piping, manifolds etc. But is their an experienced plumber out there that i can call that will both supply and install a geothermal and complete plumbing system? Finding it a little difficult to find another one to compare prices. I have one for 27.5k - this is a complete supply and fitting of all plumbing including geo system.

Anyone done this?

Eurotech in Castleblayney,Co. Monaghan (042 9740762) did do both but not sure if they still do. They did our plumbing and underfloor heating about ten years ago and I was very happy with the service. I know they are very experienced, do have a nationwide service and have been installing geo-thermal systems for a long time.
