Hola, I am Betzabe, I just finished my master degree in teaching English to speakers of other languages at Monash University. Before coming to Australia I was a teacher of English in Chile for over 4 years. I taught primary, secondary and tertiary education. I feel pretty comfortable working with adults rather than children. Now, I am quite experienced in tutoring Spanish with very good results from my past students most of them with the purpose of travelling overseas or just learning for fun.
Spanish will be easy to learn if you are really committed and interested.
Depending on your level of the language, I would say over 5 months to learn pretty much to put in practice.
