Gilberto, I really don´t know how tight your budget is or how much time you have.  Anyway, I can say to you that you can learn a lot on a budget (not spending much).

There´s the Mag Speak Up, and others, you can listen the BBC if you want the British English.

You can always have the option of a teacher in-house, or in certain courses.

What you shouldn´t say and do, is to condition your learnship: "if it is not this or that way, I give up".  Remember, where there´s a will, there´s a way, if one don´t learn from one teacher he can learn from another, with another method etc.

Awhile ago, I studied Management, and I would buy plenty of second-hand books, would use "Xerox" copies  of some books, would come early to the Uni and ask more advanced students to teach me!  My budget was tight, but I studied, I didn´t let it hamper my apprenticeship...

Well, let´s wait others disscuss and share their stories and views, I am sure that others ideas will come up to help you.
