Since we don't know what part of the world you are in, it is hard to give advice. Maybe check a local used/new camera store and see if they will take on consignment. Otherwise, places like KEH or B&H or Adorama, but don't expect more than 50% at best. If you want to get a feel, just fill out the KEH "buy my equipment " and see what the automated system gives you. You can also look at the prices they ask for selling used. Fred Miranda . com is another resource. Otherwise, find an ebay seller that will work with you for a cut.
Good luck.
