I need a person to collect business cards at a convention

I need someone to go from booth to booth and collect business cards at the National Retail Federation NRF conference in NYC Jan 12th to Jan 14th. My business in in Nashua NH and I am going to the show either driving or flying. I am not sure at this point. I need someone professionaly dressed who can just go to a booth and ask who is head of sales and get their business card. Its very easy but there are about 1,000 exhibitors and I can't get to them all. The ideal person would be someone who has worked conventions like this before and is personable. You can make $100 to $200 a day plus expenses and maybe a bonus at the end if all goes well.
