bid you a due

A salutation at the end of an e-mail that indicates the sender has knowledge that the recipient will need something from them in the future. "I bid..." as in placing belief, a sure bet; "you a due" as in something is to be paid to you. Such as a time for a task to be completed or further information on when a fucking Log Book will be returned so that I may do my part of the job in getting this $$$!
