What to charge?

I was contacted over the weekend by an entertainment agency looking for a face painter to paint cat faces on a group of dancers. I am supposed to call the lady back this afternoon with my rates. But the thing is, I have no idea what to charge.
I am thinking that it would be better if I charged per face instead of by time, because they want the designs really detailed and all unique, but I am still not sure what prices I should tell them.
Have any of you guys ever done something like this? If so, what did you charge?

I would say, charge your regular per hour rate (if you have one.) Just like you would charge for a party, belly paint, etc. The more complicated the designs, the more time you will spend, the more money you will make (and deserve.)

I agree with GIna.

you could go with hourly or you could say like $25 per person just so you don't have to guess at how long it will take you to do the extra details.

if you are going to be painting dancers its probable because they have a show to do or taking pictures.. you will need to find out how many dancers there are and what time their performace is and try to go from there

In March I may be doing 19 Geisha Faces & I'm charging $10 a face, but this is for one of my son's dance teachers & the dancers will be paying individually. I told them I'll need enough time & was told it was going to be the last performance. I'm not sure it'll work as they have other performances, are all men & will be sweating....

This one is for a party that is going to be one and a half hours long. It's going to be rainforest themed. I was thinking about charging per dancer, but I am not sure how much to charge.

I guess it depends on how many there are, how complicated the designs are and in turn how much time you have to spend.
