after school care - what do you do, what does it cost?

[geekgrrl]

I'm thinking of going back to work f/t in an office environment in a couple of years' time when the youngest is at school. A friend of mine is happy to provide before-school care, and I'm pondering my after-school options and am also trying to get some idea of how much it is likely to cost.
The school they're at does not provide after-school care, and isn't likely to do so in time. Besides, with 3 children I think I might as well pay someone to pick them up and look after them in their own home. I live in a rural area in N. Yorks. so was thinking that I might have to pay for travelling?
Would I be able to get someone just for 3 hours a day? Or do nannies generally look for f/t employment?

Yes the £6 an hour we advertised about 3 years ago. £8 sounds more normal and I pay more like £10 but if it enables me to do full time work the fact it enables that makes it worthwhile. If I didn't have after school care I couldn't do my job at all.
