Ms Hale,
My name is James Bond. I am here with my daughter, Tilly. She is five years old, her first language is French although she understands a great deal of English as well.
I have no need of a sitter for the Valentine's Ball, but I wondered if you might consider babysitting for me on Thursday evening. 7-9pm. Possibly weekly at the same time. I understand it is a little awkward timing for getting the rest to bed, although I am certain she will be happy to curl up with a book and probably doze off.
Of course, I'm happy to return the favour, or take care of anything else you might find a suitable barter.
James
