You can paint it neon pink with pretty bows if you want.. it is your bike. Personally I wouldn't got from dark to yeller - but it's not my money.
As far as cost - that depends a bit. If repairs are needed to the parts it will cost more. But to get the best answer, you might drop a PM on one of the painters on here like DucPainter or Landshark. They would be able to give you a better estimate of costs.
