The real reason that I suggested a large constrictor is because the media outlets need to be grabbed too... If you tell them you're going to do a show with some five inch geckos, then there isn't much for them to take photos of or get video footage of so they'll likely decline. If you inform them that you'll have a ten foot long burm, it's something which they might be inclined to show an interest in.
The entire point of the contact is to give the broader public a brief introduction into safe and responsible keeping and some of the wider issues which impact the industry, which includes handling or keeping the larger species.
