Instructing is great fun, you will learn a lot.. If your good at it you will acquire a strong following of students, which means plenty of flying for you.
Having said that charter is also very rewarding. You will also learn a lot, very quickly. To get a start in charter you would be better off heading up north. Go with at least 5-10 hour on 200 series cessna.
Goodluck!
