School pick up/tea time childminder/babysitter needed!

[stayingsane]

We are ideally looking for a childminder/child friendly person to collect our boys from school in Bury and bring them home (to Rochdale or to childminder's home if easier), give them tea, generally care for them, let them relax, etc. School pick up time is 3.30pm and we would be home at about 6pm. They are 8 and 4 and currently go to after school club, which is great but is leaving them overtired and grumpy - and leaving us feeling very guilty. We would all be much happier if they had a better structure to the end of their day with a proper meal (nothing fancy, just something better than the snacks they currently fill up on). I'm not sure if what I'm looking for is possible but any ideas or suggestions would be gratefully received!
