Sorry in advance if this is a daft query!
My daughter's preschool are holding a promises auction and as I have no particular skills/holiday home to offer but a love of houserwork I have offered a 4 hour spring clean. I need to make up a voucher to give to the successful bidder but what do I put on it.....should I use their products or take my own? What chores do you reckon are reasonable to be achieved in this time, obviously dependent on the state of the house?
Many thanks!
