Satellite Provider wanted for Turkey

For a total just over 5 Mbit/s and no download limits the price will be about $25,000 per month - expensive and also providing a service capacity several times in excess of your probable requirements.

Consider a lower bit rate like 1 or 2 Mbit/s with 5:1 or 10:1 sharing (at the satellite level).    With 20 - 30 PCs connected this represents some 10kbit/s monthly average per  PC, which may well be sufficient.

Cost for 1 Mbit/s shared 5:1 or 2Mbit/s shared 10:1 should be about $1000 per month.

You may need a higher kbit/s per PC, e.g. 20 kbit/s, if you have intensive traffic needs such as video or MP3 audio streaming or downloading, VoiP phone, large amounts of file transfers etc, in which case pay more.
