ROKU Channel Code Modifications

I have a ROKU channel and a general code for Roku creation development. It was created by a third party. I am not coding savvy. I want to use the code to create new channels. I am hiring someone to create new sub-menus using this code, add my videos, thumbnails in the code, etc. You are NOT creating a ROKU channel. You are simply using the current code to modify according to my needs (add videos, change subcategories, etc.)
