Hey, Dylan. I am a veteran DM here, that runs many different systems of different genres. A key to your search is letting potential DMs know what time zone are you in, and what days and hours you are available in that time zone. The site serves people around the world. Are you looking for 5th Edition? You have been watching Critical role? or other offline groups? There are groups willing to take on new players. I often run "Show you how to play / Roleplay" mini-campaigns for a few sessions.
