OPen Cart customisation and setup.

We require an experiance Opencart specialist to do the following : Setup Latest version of OC on our server Integrate with Quickbooks Setup auto updates to product db and images from a supplier ftp location and XML feeds Integrate with Googlepay and paypal. Skin the site so it does not look like the standard template. Important : We want the above system to do the followin functions. a) when an order is place by a client and payment is cleared , we want OC to upload the sales order to Quickbooks (create user if needed). Client will then get an email order confirmation with the Quickbooks sales order as the sales reference. b) the system will auto order from the supplier based on the current buy prices using the quickbooks sales order number as the reference.. c) the system will pick up a file showing what has shipped from the supplier ftp site every evening and send the client a shipping/backorder confirmation. Pricing and stock checks will be made by the site every 15mins and just before the client pays for an order. This will give us almost a fully automated we site. Store will need to handle approximately 10k products quickly and accurately. You will need extensive experiance in delivering commerical grade OC sites. Please give examples of your designs in OC and how you intend to deliver our needs. Also , please suggest any additions you feels we have missed. ****PLEASE DO NOT APPLY IF YOU DO NOT FULLY UNDERSTAND OPENCART or it's integration with Quickbooks***
