Customize Karendaria MobileAppV2

We are using Karendaria MobileAppV2 as published on codecanyon. Looking for someone to make the following changes - 1. Top left where it says Deliver To, change to a clickable Date. Default should show Today. If clicked it should show options of future dates. 2. Upon clicking chefs, it should bypass categories and directly go to menu items. 3. In each menu item, there should be a ADD button, right below the photo, and upon clicking the add button, it should change to -1+ similar to several other popular ecommerce apps. In other words, once customer goes to the chef page, he should be able to add to cart right on that page, instead of going to a next page. 4. We have customized to vertical scroll for nearby chefs/restaurants. This should be an infinite smooth scroll downwards, showing all the nearby chefs/restaurants, instead of a limited number of chefs/restaurants.
