You can't sell on BHW unless you are a Jr.VIP.
More info about account upgrades: https://www.blackhatworld.com/account/upgrades

Once you become a Jr.VIP, read the marketplace rules (https://www.blackhatworld.com/forums/bhw-marketplace-rules-and-how-to-post.203/) and then you will be able to start marketplace thread in one of the following sections: https://www.blackhatworld.com/forums/#the-marketplace.73
