Hello,
i'd like to offer you my prestashop skills.
I can create prestashop module that will take care of importing products to your prestashop store via CRON and after importing products, it can update prices or stock.
----------------------------
I work daily with prestashop over 6 years. I know prestashop from top to bottom. I am familiar with every aspect of this eshop system. From adding simple features, theme modifications, creating custom prestashop modules to overriding core files and connecting prestashop to various API's.
Thank you for your time.
Kind Regards,
Jarda Nalezny
