Professional chef
It really depends how high they are, how good they are and where they work. They might get up to 2k / 3k a month. I'm not entirely sure because, as I said before, it depends.
the least, then there are schools in which you can graduate as a chef in less than 3 years. There are others though in which you must study and practice for over 5 years... so it really depends. Thats a very general question. It depends on the kind of chef you want to be, the job you want, the status you want, the country you study etc.
