I'm not sure how music education is organized in Venezuela. Here in the United States, I'm assuming that a conservatory would be equivalent to a college level program specializing in music performance. Both of my daughters started off as music majors in college. The older one changed majors to Political Science and Mathematics and graduated a couple of months ago. The younger one is working on degrees in vocal performance and musical theater. (Vocal performance is classical.)
That's actually simplifying a bit. In addition to colleges which award Bachelor's of Music, there are actual conservatories here, too. The main difference is that a conservatory education doesn't include the breadth of non-music courses that a "traditional" college requires. It's also possible -- but this is more of a guess -- that the theoretical and history requirements aren't as strong at a conservatory as at a "traditional" university. For example, Julliard (where my father studied after his Masters degree) is a conservatory.
Unless you're planning on a career as a professional classical musician, you don't need to have a conservatory or university education. (They're not required even for that field, but it helps.) You'd do just as well by finding a good teacher. And one place to look is a local university or college with a music program. Just because the professor has a day job doesn't mean they won't take extra money for private lessons. Almost every music professor I know had private students above and beyond those they took through their school. My father had lots of students of all ages. Both of my daughters, while in high school, took private lessons from university professors. (They started with local teachers, but eventually their skills improved to the point that they needed a better teacher.) During the summer, my younger daughter is taking voice from a local university professor, piano from a local pianist with a Masters in Piano, and organ from a church organist with a Bachelors in Organ.
If this is equivalent to Venezuela, I'd just look for a local teacher to work with you. See what resources are available to you.
Another possibility to look at is what your university offers. If your university has a music department or a music school, talk to them about lessons. You may be able to take through the university with the cost included in your tuition. If not, they probably have recommendations as to potential teachers.
