Love this idea and love that your automating the process. It may be worthwhile for you to check out banner bear or pictory ai for software recommendations to help you with the content creation process.

As with banner bear you can automate creation via no code workflows and with pictory ai you could use ai to find royalty free content for text.

I have articles that may help but don’t want to come across spammy. Happy to send them your way if interested. No worries if not 🤗
