@Reyn,
Yes, I would. Actually, I'd be prepared to pay a really decent fee!
Thing is, I don't KNOW anyone who is retired (we sometimes used to ask friends' parents to do this stuff, and take them out for dinner and such....but they are all dead, or too ill, now... : ( ) and it's a bit to just trust someone.
The services, which are all police checked and all, charge a lot...especially as it can mean waiting for HOURS!
Actually, I do know one retired person.....but she runs around like chook with its head off...she'd be far too busy!
