I may not be 100% correct on this. If you go to an aviation college, you will get your ratings and also have a degree. each rating you get is good for 3 hours of college credit. You should have the ratings you need to go get a job as an instructor. No matter what that is where you will have to start to be able to get the hours you need to get a job. Depends on what you really want to do. 1500 hours is the magic number to be able to get you Airline Transport Rating for an Airline. You will need alot of cross country time, multi engine time, PIC time (pilot in command). There are other jobs that you could get before the 1500., but you will still have to be an instructor and eat bread and noodles for a few years.
