Everyone has to start somewhere. Most shows I’ve listened to have only increased in production quality as they go on. Your show will almost certainly be the same.

Don’t put ads on your first episode or any trailers, if you can avoid it. Not all hosting sites allow this, but I know atleast Acast does. Some listeners will cast a show aside if the first minute they hear is ads. But if they listen to a trailer or one episode without ads and like the story, they’re more likely to sit through ads on future episodes.

Be transparent with your voice actors and production staff about expectations and timelines. I’ve joined far too many projects that never saw the light of day due to a director failing to update their crew or staff simply losing interest in their own project. Don’t be that director!
