Product Category/Product Database CSV Build - Prestashop

Currently I have an eCommerce built on the Prestashop platform (1.4.0.17) with a template bought from them. This is marine Parts eCommmerce business. You will be dealing with Categories, sub-categories,Manufacturers , and etc. We need a Prestashop professional to import data from our suppliers dbs and adapt category tree where the products are organized under the parent categories. Again, we am looking for a Prestashop professional that already understands this platform. We have all our products readily available in Excel spreadsheets. However,we have not uploaded sincewe haven't build a better category tree to organize the product to the appropriate sections. More Info on the field split job if possible: Prestashop programmer/developer professionals only! You need to already know what you to do as this would be a simply code modification to the Product Import feature to enable multiple value separator for Product Features. Currently with Prestashop out of the box, you can set multiple values for all the columns besides features. Put the keyphrase 'presta' in the bid and message to ensure to me you have read this entire project. I am running Prestashop 1.4.0.17 The person who's most suitable and lowest bid will be awarded this project and open for new projects of the kind You must provide to me the installation documentation and rights to the code.
