JOB.
Also I'd like to know where I can learn it for free without needing to pay some fee to someone who wants to sell me on info that may or may not work.

Any opinions?
Please answer and not just give me links with affialite id's etc.

Can this be a real job?
Also where can a person learn for free even just a good basics course with no fees to pay?

Thanks for taking the time to answer
