Share with us what you know plz.

you can use the #public-marketplace here on Mpsocial and you can publish a thread explaining what are you selling, prices, and all the details.

As for shoutout and ads stuff if you are just starting you just PM users that seem interested and starting brands with low budget that look for some kind of small publicity.
