About $2500-$3500.
Looks clean, but its just not as built as other rigs I have seem sold for 4K-5K. Also your tire look likt they only have about 10-15% tred left on them if the picture is recent. If you have receipts for stuff like the gearing and re-build I'm sure you could get the higher end of that price range.
Nice rig with a good start.
