Boston Birthday Party - Nov. 7th, 2009 (looking for a referral)

I am looking for a little help...

Likely as a result of living in downtown Boston a block aware from Faneuil Hall my son has long be fascinated with street dance - primarily break dancing. So much so that he has requested to have break dancers at his next (4th) birthday party. Although I am not looking for someone to do eggbeaters in a Barney costume I am looking for (a of group) someone that is reliable, dependable and can keep the f-bomb in check while around a group of pee-wees.

Looking for something for Sat Nov. 7th, 2009 in Boston proper (place TBD)

Send me a note if you know someone or can direct me on how to track someone down.

Thanks

Carlos
