Telecoms/Internet Solution

[rufmeister]

Looking into getting a unit for my business.

Its a remote unit on a farm, with no 3G.

What I would like is:

1) Internet access.
2) Some kind of phone system that will divert from my homeline number (the advertised number) to my mobile.

Is there anything out there, or am I over complicating it, and I need to get a line in the unit, and then use BT to divert my home phone to mobile?

Was hoping to keep costs/contracts to a minimum, no 3G signal so I guess mobile internet hotspot is out.
