The artists I am agenting for will get everything done by me - hang art, pack art, collect check, mail back art & check. The rest of the mail-in is just being collected at my house and delivered to the con. The ASD has to deal with it after that. Of course, I will probably end up helping with all of it. but not to the point of mailing it back.

I get a lot of artists wanting to be agented to Cap because they charge a higher commission for mail-in, but not for agented (that's treated like attending) and they get their checks and art back faster.
