Au pairs vs childminders vs what?

[puddle]

I am about to go back to work and have a bit of a childcare dilemma

I will be working full time, in the office four days to start and then down to three days with the other days worked from home.

I will need someone to drop the children at school in the mornings when I am in the office and then pick up and have them for probably an hour at the most (dp will get home 4.20 ish)

I have looked at after school clubs but they charge a flat rate (ie until 6.00pm rather han hourly) and it seems as though the kids will just be getting into the swing of being there when they will be whisked home.

Childminders are hard to find here - we have used them before and the kids not keen.

I wondered whether there is a half way house between the two - an au pair would be ideal but am I right in thinking they have to live in? What would be ideal is someone who can come to our house at 8.00 in the am and then take the kids to school, then can pick up and bring them home/ to the park and wait until dp gets home at 4.20.

Has anyone had a person who would do that and what sort of person were they?!

Have now realised I have posted this in back to work when it should be in childcare!
