Even if this is a private sale:
The sale of multiple characters in one sales thread is allowed; however, each pilot for sale must disclose all the same information as required of any other pilot, and must also post in the thread that they are for sale. This rule does not apply to single pilots; all single pilots must be the one to open the sales thread.
Both SkillQ links do not work - you have to create a Sharelink in the SkillQ Settings.
You can find the Rules for selling in this Thread
