I used a thai company to install Telkom. For a box and dish (maybe 1.8m, not sure) on a big pole, wiring etc it was 8600baht. The box is a nano.
The card is an extra 9000baht, it is of unknown parentage!
The guy speaks good English too. A dam_n sight cheaper than our friends at jsat.
There are lots and lots of good installers around. I'm afraid we go for the easy option and an English speaker, but then we get charged significantly higher prices. For the company that did mine, do a search for sat & thai. Like I say though, there are loads out there and don't get fleeced, the expensive company still send non speaking Thai engineers round!
