I need a marketing manager

We are currently developing a fitness app (PT/client booking and management) which we would like to launch in Q2. The app is in the final stages of technical development but the team is in need of someone with a marketing background to develop the marketing plan/framework and then help execute the marketing campaign. The role is part-time and would require at least one status meeting per week with with core project team (Technical Project Manager, end client, and business consultant) a duration of 1 hour conducted remotely via zoom.
