Need help with Magento platform.

Currently we are looking for someone who knows how to import csv files (which is generated from our software) to magento platform. We are currently running wholesale business and we have price in two form. If you buy 1 item then price is normal but if you buy minimum 6 then you get discounted price. Currently we have over 30000 products and price is changing everyday.

What we are planning to achieve is importing csv file which has product code and two price column and that has to be updated everyday automatically by running automated script.

Currently, we are on CSCart platform and we are re designing our website on magento. However, our developer got stuck with importing csv file issues. He cannot import.

Once above issue has sorted then we have few more task which involves setting up payment gateways and other modification as project is still under pipeline and developer lost the hope and he is also not working for us.
