Build and Wordpress theme or plugin

Create a complete ground transportation/ transfer booking system. It has to be like [login to view URL] with all the back-end options to add new supplier from anywhere in the world and unlimited suppliers. The application makes use of Google Maps API. It uses the API to calculate the distance between two locations. This distance is returned as a string for it to manipulate as needs be to calculate the Taxi Fare. The API is also used to return a map with two markers and a potential route plotted upon it. Once the distance between the two points is returned from the Google Maps API it gets run through a series of Javascript functions that calculate the taxi fare. Variables used to determine the price include the time, the date, the type of taxi and the amount of passengers. The supplier has to "Accept" the booking which has to be sent to the correct supplier by the plugin/system, to the correct suppliers email, in a html email. Also the supplier and the passenger should receive SMS notifications from the system about the new or changed booking. To make it easier - make it work with woocommerce. Like a taxi booking plugin. So woocomerce creates all the invoices and makes it easier to manage all the bookings. Also this excludes the payment options. The plugin/software has to be responsive and modern. The right person who will build this - will get payed only after the job is 100% complete and we have tested that the system/plugin and it works perfectly. Also the plugin will become our property and you will not have the right to resell it. For everyone who will apply to this job, we will ask for a job plan. Basically how you see and would complete this job.
