Foreign Language Online

I need to learn Spanish for my job. I have to read, write, understand, as well as speak the language fluently. Does anyone know of an online service or program that teaches these skills
at no cost?
Thank you in advance for your kindness.

I need to know how to speak French but i need to learn quick but free, my job isn’t giving me Rosetta Stone so i need the best free language learning software

What are some in demand careers in foreign language. I don’t mean a job where you just use the language sometimes, but a job where the language is the focus, like a foreign language teacher/professor or a translator/interpreter.
Thanks.

What would be the best job that you could recommend? I would rather do a career in the foreign language field rather than have a career and use a different language in it (ie I’d rather be a translator then be a banker who just speaks a foreign language).
