Let my clients self-schedule the start date after approving the proposal.

I would love to give my clients the opportunity to self schedule their work. this my thought once they approved the proposal they could have the option to select the dates for the work to be done. Another thought on this maybe a good work around would be to allow a dates of service request as part of the approval process as a simple message box, that way as contractors we a know ahead of time when they would like to have it done.
