Need a customization on wordpress theme listify

hi everyone, i need to make a customization on this premium theme: listify.

With this theme, registered users can add their own listings, but there is no option to add a bookable calendar and make it payable instantly from paypal or credit card.

I need to add this feature as shown in the screenshot. is someone able to do that? and how much it would cost me?

thank you!

Can be done with additional plugins.. Check listify documentation
