Woocommerce delivery times

Looking to change a plugin I had developed from jigoshop to woocommerce, either to use the existing code or if quicker to start fresh. Basically it allows user to select delivery times. But shop owner can: Allow the admin to enter their daily delivery times (Monday 19.00 - 22.00, Tuesday 19.00 - 23.00 etc). Allow the admin to set a time (15,30,45,1 hour) so if the current time is 19.05 (and admin sets this to 15 minutes - the next time a user can choose is 19.30 Have an option to allow the time period to be set (15,30,45/1 hour) for user selecting the time up until closing time for the day. So it would then display all the possible time slots up until closing time. Attached jigoshop plugin Image a: delivery time appear in order emails. Image b: delivery time appears on order details page in dashboard Image c: plugin settings (slot interval is not required for this) Image d: plugin settings Image: e: how it looks on checkout page. Can give access to jigoshop site to see plugin in action if needed.
