I think that taking regular classes is the best way to learn a language, all the rest can be used as very good (and needed) practice. If your knowledge of Spanish is practically non-existent you could start building up your vocabulary by using apps like duolingo and mindsnacks, both are quite good apps for beginners, the latter is quite interactive. I don't know any teachers here but I'm sure that you could find someone.

You can use learning apps like Duolingo and Memrise for any language that you wanna learn. I use both and it teaches the basics up to intermediate levels.

if you want to learn here there're lots of good teachers or you might buy some course and start learning by yourself, or even better you can do both, that would be perfect. Good luck!

Hey, you could do both. You can start here or use other materials. I am sure there are plenty of teachers here who could help you out. Aj
