These are the tools I use daily. To get started you just need at least two camera bodies (preferably a third as backup), a wide angle zoom and a telephoto zoom, preferably NOT the kit lens.
I would just make sure you purchase decent pro level glass if it’s in your budget. It’s not about the gear, but that gray matter between your ears. Learning the craft always trumps buying the latest equipment. Really. Oh and don’t forget to equipment insurance for theft and indemnity.
