Your question is not so descriptive. So from what I understand is you want to schedule orders.
You can create a module/Script for creating orders programmatically. You basically need to save all your order data that is needed to create an order and with the date you want to create a real order.
You can then place a cron and call your script which will check the dates every day and if the day matches the correct day it will create an order programmatically.
But there are problems due to less description what about payments. If there are offline payment methods then the above thing can be implemented else you need much more things to think and do.
