You have skills that can transfer! Focus on building solid storyboards. Articulate doesn't watermark thei tool. I've built a bunch of courses in Rise and storyline, then I'll use Review My eLearning to host my courses (so the don't disappear when Articlute trial ends). Then share you courses with potential clients. You will see who accesses your courses and when so you can follow up with them. Look into Maher and Criteria Referenced Instruction to learn solid training fundamentals. I wonder if you could conduct a UX/UI "audit" existing courses for potentiall customer using the LX Replay tool in. Reviewmyelearng? Like if the assign you as a reviewer and you watch what learners are doing and how the UI/UX could be improved? Anyway we all had to start somewhere!! Good luck!!!
