The long and short of this post is, Were you to pay for training in learning front-end development, where would you go?

I currently work in Civil Engineering and I've become tired of the engineering field in general. I've wanted to teach myself front-end development for many years but have not completed this goal. Now I'm at a point where I would like a career change and after chatting with my wife, I want to investigate paid options with structure and requirements. This can be a degree or something else. The key is, career change.

My current situation is that I work 40 hours a week so I need something that can work with that but I need the structure and accountability of a "class". I'd be learning nights and weekends essentially.

Thank you in advance for your thoughts and opinions. All are welcome.
