Interesting offer for an internal use case :) thanks for sharing @unknown. The only thing I can suggest you is to publish an Ad post in the ~AGORA territory following this tutorial. The most important details here in SN to attract your possible buyers is the title, so make sure you use the right tag (probably [SELL] in this case?! or you can also try to publish an [AUCTION]) together with your clear intent or expectations.

Now in reality here there's no files or anything to sell here, so you'll need to have a F deeeep understanding on how Stacker.News work to efficiently deliver the nym you got early on.

Also make sure to highlight the strategy to deliver your nym to the buyer without being a scammer.

G'luck and ...

I'm not the right person to help, but @mo might be :)
