Prestashop front page css, must become more beautiful!

I'm looking for an experienced expert to customize the front page of my Prestashop website. What I need is for someone to give the page a css upgrade to make it look more beautiful and professional. My goal is to keep the same content but just make it look more aesthetically pleasing. The customization required would be at an Advanced level. Additionally, I need the content to be optimized for mobile devices. I don't have any additional front page elements I'd like to add, just a css upgrade.
