Easiest and fastest professions that's good for melee?

Hey guys, i'm 90 with my warrior now, and im going to do only PvP (arenas).

What is the best profession for warriors in arena? I don't have plently of gold, so i thought maybe BS+mining? but then I have to get rid of mining or BS and get like engineering or something else? Doesn't that require A LOT of time?
