I Need A Quinceanera Choreographer

Hey yvonne angel instead of a quinceanera i will have a sweet sixteen. It is going either in the Central Valley or the Bayarea. I still have a year to plan it will be on april 30, 2011. I want a Grand entrance, a vals and a surprise dance. I think 3-4 months prior to the party is a date to start practicing. I will have at least 6-7 chambelanes but i dont know if i will have damas. Do you guys pay by the hour. How much will you charge over all.
