How to add "SHIP TO STORE" & "DELIVERY" to payment area on product page. (Enterprise Theme)

I am looking for a way to add two options for payment from the product page, such as used by Home Depot or other large retailers. We offer products that we order and re-ship to customers. This would allow us to display two dates ranges for product arrive. For example “Ship to store” would arrive in 3-5 business day, and “Delivery” to the customers house would arrive in 5-10 business days. I am looking for a way to implement this into our site. We are currently using the Enterprise them and do offer shipping or in-store pickup. The big difference I am trying to change is for this to appear on the product page itself with date ranges included. Thank You.
