The 3 roles can be conducted by one or 3 volunteers, especially if one task is specifically of interest to you.
Our client loves her horses and continues to look after them, but would like someone who can audio describe as she does so.
Our client sells plants at market stalls, so requires someone who is happy to assist in setting this up each week. The tasks may include creating and applying labels etc.
The last task is a front rider, so our client can go for bike rides. Even if this can only be to the front gate, which is a distance away.
