Local authorities are likely to consider supporting initiatives that help local shops and services, have a look at the High Peak case study. Some local authorities have gone further than this and assisted shops financially. See the community hubs section for more information.
And of course local shops and services are likely to be keen to join in. See if there is a local business association already that could be a good first point of contact.
There are also a number of national bodies and initiatives that may have more information and ideas:
BLoC, the national buy local campaign
Association of Community Stores
Federation of Small Businesses
