You don't have enough money to start approaching the professional level at all
if you want any kind of decent camera, it'll HAVE to be film.
The average nice sports lens costs way, way mor ethan 400 dollars. Sorry. I'd go with a nikon n80 if you can find one used, or a used f100 with a decent lens. Maybe an 80-200 f2.8. Yes, I'm telling you to save up a butt ton of money, and not buy some halfass cam that you will regret
