kaon price comparison software help

We bought the script to use on a new website with heavy server to import at least a million products. But after importing its really hard to get all the categories on the right spot, and all products in the right categories. Because the merchant all uses different category names for the same product. I really need a hand and help to explain how we can setup the category structure. Only bid if you have good expertise in working with the software and a proven record or feedback for this. if not, just not bid unless you are very clever in creating me category structure where the products is in the right place There is also a way to export the categories and change the id 's to fit the sub id's and import it back
