Answer: Parker should close the deal quickly
Explanation:
Giving Kitchel so much time to go over the proposal is not ideal because in that time events could happen that would ensure Kitchel stayed with their current supplier such as the current supplier finding out and offering better terms thereby enticing Kitchel to stay.
It is imperative therefore that Parker close the deal as quickly as possible. He can do this by offering time conscious incentives that require that Kitchel order fast, he could even go meet Kitchel in person and press his claim and even hit hard at the weakness of Richmond's current supplier by stating that he would deliver things ahead of schedule.
