Wordpress Courier Plugin

Custom Wordpress Plugin Development We need a plugin developed for one of our clients who runs a small courier company. The basic function of the plugin will be to calculate the distance (google maps api) between two addresses, calculate a quote based on the distance and service type selected, and then take payment from the customer via paypal. Detailed description of requirements: There are two main types of clients, ad-hoc clients and account holders. Both must be registered to book a delivery and also must have access to their account history where they can check the status of their deliveries (only 4-5 different statuses required), and to their profile where they can update their details and preferences. Non registered users must also be able to see and use the quote form and registration should be performed before checkout. The main difference is that ad-hoc clients are required to make an upfront payment when booking a delivery, while account holders are not required to make a payment, they will be billed manually on a monthly basis. All new registrants should be handled as an ad-hoc client, and the site admin must have the option to upgrade them to account holders, or vica-versa the admin must be able to downgrade a client. Clients must be identified by their user role within wordpress, one role for ad-hoc clients and 3 different role for account holders is required. Pricelists used for the calculation for ad-hoc customers and different role account holders must be available to change by the site admin within the wordpress backend. The project is to be completed in English (UK). When replying please quote reference: PS1401, just so we know you’ve actually read the description. Any questions please let us know.
