You have to get a lot of certs and ratings to do any type of professional flying. The point of entry is 1200 flying hours, which is a lot of time if you are paying for it. So, to build the time you will need to become a flight instructor. Instruction in aviation is stepping stone rather than a destination like in other fields. You can think about all this while you obtain your private pilot certificate, instrument rating, commercial certificate, instructors certificate, and multiengine rating, and later your Part 135 signoff. That will keep you busy for a year or two. By the way, welcome!
