Seems like you're playing a few roles, but the chief ones would probably be:

Product Manager: You take business goals and turn them into technical requirements, then ensure the product gets built.

Project Manager: You take technical requirements and ensure that your team delivers on those requirements.

User Experience Designer: You create mockups for products which can be implemented by the technical team.

I'd put together a portfolio of your work and send it off to a few companies, as that might be good enough to land you a job.

While "product manager" has different meanings at various companies, I'd expand the description of PM to include all the wrangling of sales, marketing, and customer service that goes into shipping a product as well.
