Convert an existing Drupal Website to an online store

I need to update a current website from the existing one which is a basic Drupal site to one with an eCommerce ability to take orders for physical book deliveries. The current draft website is located at ecs.sabeex.co.za. I want to establish a “bookshop” online to sell some of the paper books that are currently sold off a one page PDF Order Form that is downloaded. What I want on the website is: • Update of Drupal to latest core along with all modules. • Setup of UberCart on the website • Setup of the Products for sale according to the booklist he has. Each product would have the following basic information: o Product_Title o Description o Contents (contents page of the book) o ISBN_if_applicable o ECS_Code (Stock code) o Category (Type of book) o Cover_Colour o Price_incl_VAT o Image • Packaging and postage would be a variable based on the person’s location – again a standard UberCart function (or addon module I forget!) • Easy editing of the prices for each product from a single “price list” if possible (a new View if UberCart does not have that Functionality) • Generation of the invoice as an email attachment from within the shopping cart to the user (and the admin person) with broad reports as required on the number of books sold per month, at what price etc. • Incorporation of the FastPay payment gateway Please evaluate the existing Drupal 7 website, and provide me with a quotation and timeframe to set up the shop. I need the project complete by the end of March 2016.
