I'm seeing this thread a bit late, but I highly, highly recommend Joe Rooney at Rooney Tunes Entertainment (based in Dobbs Ferry). We booked him for our daughter's baptism as well as her first birthday, and I will say that he made the party! He was great with the kids and I didn't have to worry about anything as far as keeping them entertained. His prices are also extremely fair. I hope this post reaches you in time to book (not sure when your event is). Good luck
