Is it possible to buy personalized video message from the guys at all and if so where from, please ?

Looking to download a personalized video message for my daughters 18th birthday, she's a huge fan and has supported all the campaigns too buying all the shirts etc so I would like to try to get her a personalized message
If anyone knows if there is a video out there anywhere that I can download saying happy birthday with ou with the 18th and also with ou without her name, Aimee ou alternatively somewhere like celebvm where they are listed to purchase a recording, thanks x
