Prestashop product list css creation for display

I am looking for a Freelancer to help with a project related to creating a customized CSS stylesheet for a product list on my Prestashop website. This project is for an existing business and I know the general structure of the stylesheet that I would like, but need help with its creation. Specifically, I would like to display the product list using a grid style. If you are experienced in this type of work and are interested in this project, please let me know.
