Presume the local estate (rather than a friendly local farmer who also wants broadband) own the higher land around the village, so there's no obvious location for a repeater site 'down' to the village using a wireless solution?
Don't suppose Call Flow are interested in total one-offs, but have you tried them? They've been delivering an FTTC solution in Kent, and perhaps more relevant, near Alresford, Hants, under Govt funding looking at delivering to the final few %. May be able to do something cheaper than BT?
Presume despite your username it's not Beaulieu itself you're talking about - Boldre
perhaps? - as HCC/BDUK were looking for cabinet sites there - see here
- I assumed they were going ahead with upgrades for these areas, and the HCC Superfast Broadband Programme map implies this - or did they change their mind/fail to find a location?
