I would recommend it to anyone, I did it after loosing my job and to get my fitness back after being unwell for a few months and it really got me back into the swing of things.
Look up the contact details for these sorts of places in your area and give them a call, in my experience they are always after happy helpers

edit - I forgot tto mention - you don't need any prior experience with this sort of thing and certainly don't need green fingers (particularly if you are doing rhoddy clearance)
