Sports Cards Project

I'm looking for a skilled freelancer to assist me with a website design for a sports cards and non-sports cards marketplace. The project involves uploading a website theme that I can purchase or you creating whichever is less expensive after all I am a new business. Homepage, I will be looking for creating sections for Baseball, Basketball, Football, Hockey, Soccer, Pokémon, Comics, Graded Cards and Other. Right now, I am uploading between 50-100 sports cards per day I currently have about 700 sports cards uploaded in my Shopify back end. I would like for the home page to quickly show as a marketplace. For instance, Headline Baseball, and having approximately 4-5 grids across for baseball sports cards and then being able to go to pages of baseball cards. This will be for all sections on the homepage. I currently have a banner and a logo which I have attached. I also need for it to be easy to add more cards and pages as I grow my inventory, unless you will be available as I need adding of more products. You can guide me on apps that you believe are necessary for this project. Well, I am sure there will be changes as we go along and other areas of interest that will be added. I have many other questions but at this time I would like to concentrate on the look and feel of the homepage.
