Divi WordPress Theme - Install Custom Post Types - Racehorse Roster

Our website is [login to view URL] We own horses (racehorses) and want to build a roster with functionality similar to [login to view URL] . Our WordPress theme is Divi by Elegant Themes and has a page builder built in [login to view URL] This should be done with custom post types and then functionality to allow it to display in grid and perhaps other view formats. We don't want to use the built in Portfolio types and adjust. This needs to be a custom type post (the type is "horse"). When you click on a particular post (or horse) you get the details and it can look similar to this [login to view URL] Thank you and look forward to hearing from you! Prefer someone that has experience with custom post types and of course Divi would be nice.
