Looking for a prestashop developer

my prestashop freelance developer suddenly stopped. So i'm looking for somebody new. First i want to start with a small task. I will go on holiday for 3 weeks, so i need a popup that mentions that orders can be placed but will only be handled after our holiday. We have 3 shops running for 3 different countries. Important is that all visitors need to see the popup in their language: NL, FR. The popup has to appear for every visitor. So also the ones that arrive directly on a product detail page. And i also want to show the popup for a second time at the checkout
