Get to know a sympathetic university professor in the area you're interested in. They can help you publish, including, vitally, providing feedback on the work that you've done and how it fits into the current state of the art in the discipline. And they can advocate for you and get you into a grad program at their schools. Honestly just find a few that have research areas that match what you're doing and email or call them.
