Offer an in-house movie night where the local hall or your grounds can be used. The movie could be outdoors for an even greater pull value. You’ll need a projector, sound system and a white wall (sheets can be used for great white wall finishes also).
Sounds simple, and it is! That’s why it’s a great idea. Offer a community dog walking service. Most people would love the idea of someone taking the responsibility of walking the dog off them once a week at least. That’s where your group comes in.
