Using the current online store information and design concept, create a Magento Community E commerce store. You will need to be sure that all criteria is carefully planned and implemented so that it works effortlessly with a cross channel marketing software application which will synch with Amazon and Ebay. Current merchant services must be setup and work properly. There are approximately 2000 items and I have another freelancer formatting each picture to Amazon specs. He can have the entire item list organized in a spreadsheet as you specify, it would be imperative that you outline the specs and have them imported so that channel marketing app works properly. There is plenty of documentation, forums and contacts for this to be completed properly without burdening the website with unnecessary coding which might slow down the site's functioning.
