The former guy appears to have started his own version of a celebrity Cameo service

Getting a personalized greeting from Donald John Trump is about on par with gnawing on Trump Steaks™ gristle or being spirited away to a Florida fen by a mass of Trump-branded bedbugs.
It’s not for me, but hey, surely someone will bite. He may even get more than Barry Williams, TV’s Greg Brady, does on Cameo. For those unaware, Cameo is a popular website that allows mostly washed-up celebrities to record personalized messages for people’s birthdays and graduations and other events that could use a little boost of, say, Kirk Cameron.
Again, Trump won’t get a penny from me, but presumably there’s still a market. For now, anyway.
