Modify existing Prestashop

Hello I have a Prestashop with integration with [login to view URL] (dropshipping). Website is on VPS (OVH). Bigbuy installed all required plugins/modules on the shop and configured the server, but I need to further configure it so order sync works and so on. Basically just configuring existing prestashop and it's modules (probably no programming needed). I assume you have Prestashop experience you can show and Linux experience (LAMP). In order to make sure you read this info please mention following in ur comment: icanhazpresta Thank you for your time.
