Install Joomla, Virtumart, a Module - Configure and Transfer Design

We currently have a website - [login to view URL] - which uses very old versions of Joomla and Virtuemart. We need them to be updated, however it is a little bit more complicated due to the nature of the site. When the website was originally created, we had a custom made Javascript calculator made which calculates a value from 2 dimensions that the customer inputs, then this is added to the cart and the customer completes the order. So to get around this, we are suggesting using Joomla, Virtuemart and the Virtuemart Custom Size extension. So you will need to :- 1. Install Joomla (latest version of 3) 2. Install Virtuemart (latest version 3) 3. Install the Custom Size Extension module and configure it so it works in the same way as our Javascript calculator does now [login to view URL] 4. Transfer the existing site design and all the pages to the new versions, so that the site looks exactly the same as it does now, except it will be using the latest versions of Joomla and Virtuemart and it will be using the Custom Size Extension instead of our Javascript calculator 5. Ensure all the configuration, is exactly the same as the current site 6. Install the same or similar shipping module as now, which works out the shipping cost on the post code. We have Cpanel on the server, so you will be able to do the Joomla install from Installatron within Cpanel. As the site was recently hacked and lots of files infected with Malware, please DO NOT transfer any files over. Only copy content, text / images etc manually and don't transfer any actual files to ensure the new installation is not infected. So when you are finished the site will look and work in exactly the same way as it does now, except it will be on the latest Joomla, Virtumart and with the new Custom Size Extension. We would prefer someone who has used the Custom Size Extension before as it may take some configuring. Please ensure you have read the full project description before bidding. Thanks
