I use elegant themes Divi for this site and I think its a great solution. For the price of a single premier theme you gain access to all of elegant themes. Including many plugins too. The Divi theme is the crown jewel of the collection with a specialised divi builder which makes building websites easy.
Production Crate has a bunch of resources like audio effetcs, music, visual effects and video making templates that I use for my game and help with making marketing resources.
Has free products and a reasonably priced premium membership.
