Economic connection in rural Ghana needed

Hi,

I am trying to help a charity get online in rural Ghana.  They have little money, so I am trying to find out if some kind of economy connection is possible.  The main concern would be running costs, since capital costs could be covered by sponsorship, for example.  Entry level systems are being considered as a first stage.

I am going to contact all the companies on the Africa page, but wanted to poll people here for ideas.  I used to work in the internet field, but that was dial-up and leased lines, satellites are over my head, excuse the pun!

Thanks,
David.
