Dear Mr/Mrs
Thanks for bringing the availability of the rooms to my notice. I am alright with the cost of booking, I want you to get back to me with the total quote of the reservation so that I will know the total amount to be charge on my credit card. I want you to know that I will be the one responsible for the payment of the reservation so I am making the payment in full and not part payment because I will need to show them the proof of payment which is the charge slip before they check in at your place. I need a quote before I forward you my credit card for the payment.
I await your urgent response.
