Marcus the air conditioning engineer has been installing satellite for the last year now. He is a good bloke and, I believe, trustworthy. I saw your posting on the Thalassa forum, are you living there? If so, I believe Noreen is the President and should be able to give you the whys and wherefores of such an installation. It would be better to find someone in your block with a dish and ask to connect to it, that is the cheapest way (cost me €75). Buy your own satellite box from the UK and all you then need is someone to run the cable from the dish to your box (cost me €60 with Sol Sat but can't think of their number). I think they both advertise on Viva Almeria, ACS Air Conditioning ans Sol Sat in Turre.
