how much $ is it worth

[CoorsMan]

Hey I want to sell my flat bed trailersingle 3500lbs axle and I was wondering how much $$ I should sell it for. Its 6 x 12, with 1 foot angle iron sides. I can put 3 quads on it side ways. Has a removeable tire rack (lockable) for quad tires. Two 10 gallon air tanks under the bed, holds up to 165psi. plumbed out to 3 points on the trailer for quick connect air fittings (2 on the passager side and one on the driver side) Its has 2 fender boxes for storage, and its has an electic powered ramp. Just push a button and the ramp goes down and opens up. its has a onboard battery with charger. running lights and backup lights

anyone out there know what I could get for this trailer?
