PRESTASHOP - Order Processing Module

This project is for the creation of a Complete Order Process Module and is only open for very experienced PRESTASHOP Developers. I have a B2B Portal Website (non ecommerce with the backend payment system switched off) - it is a self service portal for business customers who have an agreed credit account in place. We have already altered the standard shopping cart to become a "quote cart" where customers create their own quotes and save them. I want to be able to use my Prestashop Portal to handle the full order process - utilising Customer Records, Customer Quotes, Customer Orders, Suppliers, Supplier Orders, Delivery, Invoices. ALL of these areas need to follow a streamlined "Workflow Process" This workflow in its simple form is : Customer Record to Create Quote to Customer Places Order to Supplier Order Created to Delivery to Invoice. Please note that I DROP-SHIP products from my suppliers direct to my business customers. My Prestashop Portal contents (product data, suppliers, stock, costs, data, images etc) are currently being supplied to me via an aggregated ftp file. A series of templates/views will need to be created for all records and subsequent navigation views will also need to be created. Super-User access must be created where my sales people can log in and create quotes on behalf of their business customers. It is even more important for me that ONLY VERY EXPERIENCED developers supply a bid for this project (if this work is going to be too expensive then I will look at using vtiger and integrating the two applications with workflow processes). I have a very detailed spreadsheet that fully explains the complete workflow - ensure you request this when you bid !
