I have been cc'd on the emails and I feel that you would not be the RIGHT person to conduct photography services on the day of my sister's (Alexandra's) wedding for the following reasons:
Please respond to Alexandra by latest Monday afternoon and cc' me as well. If we don't hear back from you, we will move forward with somebody else.

Commercial work may be done on a PO and NET 30 but I would never handle a wedding like that unless I had pulled credit and had a contract in hand.
Right on, those terms are usually applied when you have a filed a credit application with the vendor.
