Child minders in Preston UK

I am moving to Preston in fall of 2007 for school.  I understand my daughter will be able to attend British school as she will be 4 1/2 part time.  However, I will need someone to watch her while I am in class for 3-5 hours 1 night a week.  How much should I budget for this and where should I look for a trustworthy person?

Thanks
Christina
