Gigaclear is the Rolls-Royce solution - high quality but expensive and you may need a community of at least 500 properties to have a reasonable shot at persuading them to take an interest. If satellite systems are too expensive for many, then this won't work.
For smaller scale communities, the best option is likely to be fixed wireless. There is a fixed wireless operator called Allpay with a service in Herefordshire who might be interested in expanding regionally. You can also search the members of INCA (www.inca.coop) for other small fixed wireless operators.
The majority of small wireless systems operate on a self-help basis. There is an increasing number of such systems in Scotland of our geography. Read material produced by the Tegola project (www.tegola.org.uk).
There are two key requirements for any wireless system. One, a high point that can be seen by many potential subscribers - perhaps your church tower. Two, a source of backhaul - i.e. a fibre link from your local distribution system to the internet spine. The fibre exists but getting access to it is either expensive or administratively difficult.
Very small systems (< 10 properties served) are easy and cheap. Small ones (10-50 properties) require more effort but may not cost more than £300 per property. For more than 50 properties served you may be able to attract a commercial provider if your geography is favourable. You will need to get firm commitments to take up the service pretty early because vague intentions are not sufficient to justify even quite small investments.
What you will learn rapidly is that there is a reason why almost everyone prefers to sub-contract the work to BT or another operator. Promoting community networks involves a lot of effort. But it is the only way by which many small communities are likely to see a significant improvement in their broadband service over the next 3-4 years. You can send me a PM if you need further information.
Edit: Let me add one further point. On checking I see that much of South Shropshire is an AONB. I live in one of the Scottish equivalents. The features that lead to landscapes being classified as AONBs complicate the development of wireless systems but they also explain why you won't get any other form of broadband quickly. The planning restrictions that are associated with AONB status may require special permission for wireless installations. I can provide some guidance but you should talk to your local planning department at a fairly early stage.
