[HANASHIR:12681] rates?

Shalom y'all!
Help! I have two upcoming gigs, and am not sure how much to charge.
One gig is an "Up All Night" JCC event which is raising $ for Israel. I would 
like to also incoprorate sponsors to donate $ to the cause (for every X 
number of songs I play, they will donate X amount of $). Not quite sure how 
that would work, but it;s a thought.
The other is a BBYO retreat where I'd be leading t'fillot and a songsession.
Thanks in advance
Shabbat Shalom!
