Add shipping option : Delivery times

Hi,

I would like to know if it's possible to add an option for delivery times?

For example, I would like for the customer to be able to choose if he wants to get his delivery between 8am-9am or maybe 4pm-5pm etc.... before paying. (it won't change the price!).

Is it possible with a template on wix? If not, do you know how much it would cost us to hire a web developer for such an option?

Thanks in advance!
