Okay, so start with an intro post over in the welcome new members section. Then go to the buy/sell/trade section and read the stickies. Finally, pick the correct sections and post the required details for the things you want to sell. Once you agree to terms with someone do not change your mind, add new requirements, miss the meeting or otherwise dick the other party around without his or her consent as doing so will cause you to be banned, this is one of the few hard and fast rules. Did I say to read the stickies, if not, read the stickies, there may be a test.
If you are in the business you should sign up as a vendor, it’s cheap.
All that said, and although your post is in the wrong section, welcome to CFF
