What AI Courses should i subscribe to?

Hi All! any AI engineers who can assist? i am a C# VB winforms, aspnet, mvc developer, I want to upskill and branch into the AI side of developing. Could i please have some minutes of your time and get a a good list of courses to purchase? there is too many out there and i dont have the moneys to subscribe to all of them, or to wrong ones. I know python is a prerequisite. Also from the list you provide, at what point can i add that im a AI engineer on my CV. Thank you in advance, and i appreciate your time.

The more specific with the course the better for me. Again thank you.
