I'll say the same thing to you that I/we say to EVERY member who joins and their first post is trying to sell something.
We are generally very suspicious of brand new members hocking high dollar gear. You don't have any track record here, or the credibility to sell a $4k camera. SO...
- Where else are you active online that you have a better track record? Other forums? eBay?
- Can you upload a picture showing the camera/gear with a piece of paper that has your username and today's date?
