Back when I used to do these things in New Zealand, you could encode a  
155Mbit/s symbol rate into a single C-band transponder channel. On  
IntelSat 177E which we were using at the time the service we could  
obtain was limited by available spectrum on the satellite (this was in  
the days before Southern Cross was commissioned, when PacRim-East was  
essentially full, and there was a brief boom in IP over satellite in  
the Pacific).

IntelSat spectrum availability and pricing always used to be public.  
All that remained was to identify a suitable signatory in a fibre- 
connected location to provide an uplink, and purchase some transit.  
Quite possibly there are other approaches for buying an integrated  
service, today.

No doubt there are other satellite operators that should also be  
considered, but IntelSat pricing might give you a useful baseline.


Remember that if you're looking for a duplex service, you will need  
spectrum at both uplink locations. Also consider that you don't  
necessarily need the same RF bandwidth at both ends if your traffic  
requirements are asymmetric (e.g. you might be able to combine a 155M  
[symbol-rate] uplink from the remote location with a much narrower  
local uplink).
