505718 Website e fulfilment integration with Smiffys.com

I have re submitted this project as i am now using OpenCart with Joomla, I have also included attachments to assist in understanding requirements I am currently developing a e commerce website and have identified a company who will dropship products ([login to view URL]). As part of the contract i will need to set up integration with their site. I require full integration with the client and this will enable the site to automatically update categories/themes, products, costs and stock details every hour. the integration should enable the clients site remove obsolete stock etc. Once a product on my site has been purchased and payment recieved, my site will need to automatically send a detailed XML file to Smiffys enabling the to dispatch goods. I will need to be able to manually adjust details if required and i will need to be able to add my own products to the site and manage these separately as these will not be stocked by Smiffys My site is currently set up using Joomla and has JooCart (OpenCart) installed as a component. This is my first attempt at ecommerce and funds are limited so I am keen for this to be done right first time and the use of scriptlance comes on good recommendation. Thanks for looking Alan
