How much can I get for my 2012 kawasaki ninja 250?

I want to either sell privately or go to a dealer and trade in my 250 for a bigger bike. It is a 2012 Kawasaki ninja, candy green, with a big EVO S slip on exhaust, and LED lighting to illuminate while night driving. It has 1865 miles on it, the tires are stock and are in great condition and the bike has never been dropped. The 250 is awesome and I honestly like it but i feel i need a bit more power. Does anyone have an idea of how much I can get trade in value and private sell?
