Wordpress Ecommerce Plugin for Service Company Websites

Looking for an experienced coder who can develop a Wordpress ecommerce plugin. I will be using this plugin for multiple websites to process payments and book reservations for service companies that I own (cleaning, tutoring, window washing, etc.). The final product must provide a very clean and friendly user experience. I don't want unnecessary popups, and customers must be able to easily navigate between the calendar where they select their day of service and the subsequent menu where they reserve a specific timeslot for their service. Please read the following details carefully before submitting your bid and portfolio for consideration. I want this done ASAP. On the frontend of the website, you will implement a shopping/checkout experience within a single page. Customers must be able to (1) input their personal information (Name, Email, Phone Number, Address, City, Zip Code) (2) pick from services available in a dropdown menu (3) reserve a time and date from a date/timeslot calendar which displays remaining available timeslots on specific dates (reservations cannot be made sameday or next day, reservations only available starting two days from time of booking) (4) input a discount code (5) pick additional services through check boxes (6) select frequency of service (7) pay in advance using either Paypal, credit card (processed by Paypal), or pay at time of service with cash/check (8) see their final price updated in real-time next to the book appointment button Here is an example of what we have in mind for the frontend of the website: [login to view URL] On the backend of the Wordpress website, we need you to implement a functional admin section for the plugin. Admins must be able to: (1) browse and modify all reservations that customers make through the online shopping/checkout experience (2) browse and modify which services are available to customers at what prices in a dropdown menu on the frontend of the website (3) browse and modify which timeslots are available to customers on specific dates in the date/timeslot picker on the frontend of the website (must have control over specific dates, in addition to weekly patterns of timeslots which repeat, so that we can override the weekly patterns and remove availability of reservations on holidays) (4) browse and modify all discount codes that customers can use through the online shopping/checkout experience (5) browse and modify which additional services are available to customers through check boxes on the frontend of the website (6) have control over how many reservations are possible for each timeslot on specific dates (7) link the plugin to our PayPal account in order to process payments
