PrestaShop Template Grid for Products Edited

We would like someone that is skilled in the development of Prestashop templates, we require our existing Prestashop template to be edited, the products page currently only allows one product on a row, we require either two or three products on a row, the current grid set up doesnt allow more than one at a time. Please review the image, you will see left side is current grid set up, the image on the right actually has 4 products on each row, this will be to many, but the attached images are just to give you an idea of what we require. Would also require the template to allow us to either increase from 1 to 2 or to 3 products per row.
