Startup Idea : Renting telepresence robots at conferences

For large conferences, people have to choose whether to pay $500-$2000 (plus flights and accommodations) to attend a conference, or not go. We would sell to events and conferences who would list a much cheaper, per hour, ticket price underneath the main ticket. That way an executive on the west coast could attend a conference on the east coast for half a day, get the information and meet the people they want to, and pay very little. Main draw for conferences is notoriety. We come with 20-30 robots, and everyone at the conference sees the robots moving through the crowd and never forgets it! Starts with a website and some passionate hustlers!
