Best sort-of-professional cameras?

Hi! I'm only in highschool, but i'm considering photography as a future career. Right now I have a (not recommended) Nikon coolpix L110. I am looking for another camera within my price range (i'm going to be making money this summer so probably $300-$800). I want to look for some amateur versions but I also want to consider some more-professional versions (like that I could use on a photography internship taking pics at a wedding, portraits, etc.) I'm not very experienced when it comes to cameras so I need advice! Please Help! Thank you:)
