there are a million and one ways to achieve a career in aviation. theres fast slow and everywhere in between. you need to research some schools near you and figure out your timeframe, budget, goals, motivation level etc... i can tell you that it will cost more than 6k for a ppl and then countless more for commercial cfi, multi. I would look into a community college program nearby that has a decent program. WIth those you can get financial aid, scholarships and use VA benefits if you have them. The structure of a college will more often then not get you done faster with the structure. Part 61 at the local FBO can get you where u want to be, and can offer great instruction. But if its a career you seek i would recommend a college and get a degree out it also.
