By the way, I wonder if you have baby sitting service.
We do have very reliable part-time baby sitters.
I wonder if you can look after the baby for us, please?
Our Housekeeping Department has very good baby-sitting service.
My husband and I want to go out tonight. Could you contact a babysitter for me?
Do you know how much it costs?
That sounds reasonable. I'll call them now.
Please sign this confirmation form, and I will phone Housekeeping.
