What is the best model for Marketing purposes for a specific industry?

I would like to use AI for marketing purposes, such as creating “our avatar” based on the data of our clients. I don’t have too much specific data though.

I would like to train the machine to create our avatar and then create marketing pieces like emails, blog posts, ads, etc.

In short, I’m looking for creating a model that has marketing knowledge and uses our information to create content.

What is the best model available for me to use in Hugging Face?

Thank you
