Write clear and actionable Epics and User Stories.

I am looking for an experience product manager or Agile Product owner to do user stories writing exercises, that vividly explain requirmrnts to my developers. You must be very sound with high-level Epics and user stories for auto renewal subscription, discounts, referral codes etc. I will prefer we do a video call so I can grasp your explanation and learn, while we work on these requirements together.
