Hello Potarnike (si un an nou fericit :D),
We have a firm specialized in PrestaShop so you can bet that our team will get the job done fast and with great sense of responsability. More to it, I just finished a while ago two automatic imports systems based on xml data and rss feeds(the latest was for a online shop actually).
We ask for 4 days so that we have plenty of time to test it(chances are it will go faster :D). Hope to hear from you, Cheers
