Where would I put a sales thread for twitter/instagram followers?

Hi all, new member here.
I currently run a succesful social media shop on a few other forums and got recommended to visit this forum so thought I would check it out. Seems good so far!

My question is what subforum should I put my sales thread for social followers/likes? If I buy an onyx account can it go into the premium market?

Thanks, and pleasure to meet you all!

I would put it here- http://www.forumkorner.com/forum-31.html

Since you are offering a social media service.
