How can I set up scheduled in-store pickup options?

[Naphoenix]

Hello All,

I hope someone can help me. I am having the worst time trying to set a scheduled in-store pickup. I want to be able to have a product, picked up, but I as the admin/store want to give the customer a choice when they can pick it up, and then the customer can choose from a list of my choices. Please help. I have tried every app that I could find, and while some say they do this, I have yet to get one to work. So I need the store to:

1. offer in-store pickup 

2. the store has limited times it is open, and since it is a bakery, they need a day or two to prepare the order, so 

3. A calendar with dates  and times the customer can select to pickup their order

Any help/insight would be appreciated.
