Best Land Rover specialist in the Sheffield area?

I'm looking for the best Land Rover specialist in the Sheffield area to take my Disco 2 td5 to. I've seen people recommend S Dranfield in Stockbridge, but for the life of me I can't get through to them on the one phone number that I can find. Does anyone have an up to date phone number for them, or can recommend anyone else who isn't going to run with my money? Thanks.

Sheffield prestige. They are all ex landy mechanics.
