cron import script for prestashop with 6000+ products

I am designing a website on the prestashop platform I need to integrate our website with a product supplier. The supplier provides us with a .CSV file we can download daily via their ftp folder to update product prices etc.. I am looking for someone who has experience in doing this and is able to set up a cron script to get the file on a daily basis. On import of the .CSV we also need to calculate a couple of price changes in the file and create 2 new columns in the database for the products. On import the suppliers price is their wholesale price we need this price to be marked up and displayed on our site in the correct fields in the site database these being 'price excl VAT' and 'Price incl VAT. I need the videos to also be handled with a necessary player (perhaps a video plugin) played from the hosts url which can be changed easily. I would love to hear from anyone who can do this easily!
