I think you will have better luck in ebay:
A couple weeks ago I saw a pair of JK front (no rears) half doors with uppers sell for $1,900.00 plus shipping.
I sold a pair of JK rear half doors (no uppers, no fronts) for over $1,000 plus shipping.
Dealership quoted me $4,500.00 for full front/rear half door set painted, non-tinted uppers; so for the buyer that does not need to repaint, your asking price is not farfetched.
Good luck with your sell.
