When you do put it up for sale, no matter where that may be on the internet, don't forget to write up a post about what it is that you are selling, put a link in the "ad" on the ecommerce/auction site out there.
Most importantly, when writing your post up, one of the tags needs to be "classifieds".
it is that simple and if you don't like waiting, then simply copy paste a link to your post in the steemit chatroom:
