Build a Website

Need a Wordpress theme created from scratch with the following home page as a template: Need this site to have the following functionality: -customer needs to be able to select their "group size" and a date/ time using a calendar to see availability which should sync with Google Calendar. -Once they have chosen an available date and time slot, I would like them to be re-directed to a shop page where they can pick a certain number of products off of the page based on how many people are in their "group" that they selected in the previous step when choosing their "group size". -After selecting one product for each person, they should be redirected to a checkout page where it will confirm their date and time of delivery, ask them their delivery and billing address and work with Stripe and Paypal. The products they chose should appear in the checkout page but they should not have prices. -There should also be an internal calculator in the site that selects how many people they selected are in their group and depending on what number it is, have conditional logic. -If the number is between 1 and 9, they will be charged $40 per person. If the number is 11-19, then they should be charged $35 per person, and if they have 20+ people, then they should be charged $30 per person. And once the customer gets to checkout, it should take the number of people in their group and multiply it by the appropriate amount based on the conditional logic. And then, once they complete checkout, they should receive an email confirmation and I should receive an email and text message notification,
