Hello @Havilah thanks for reaching out. Unfortunately, however, we're not accepting new services on Airsob at the moment because, like you said, we're currently in private beta and we're already filled to capacity. We even have some other guys waiting to join in when we can accommodate them.
If you are interested, you can send me an email at firstname.lastname@example.org and I'll add you to the list so I can contact you when something opens up. Again, so sorry if you need the service urgently but this is the best I can do at the moment.
PS: Thanks @Engrtitus for notifying me.
