Here are some parts if you still have not built the bike yet. Close to budget. Not the best, but they will do.

These are as close to $600 as I could get. The bike has very noisy brakes. I own the same one as an ebike. The derailer is crap, but for $13 you can buy a Shimano tourney. The crankset is plastic, I replaced it for $34. And the brakes I replaced with SRAM Avid BB5 calipers, they are dead silent, but cost $74. There is some good parts and how to make them better. Good luck.
