So I have purchased a booth at the Indian Wedding Expo this weekend.  I am looking to market to indian brides for their Sangeet or Mehndi party. http://www.indianweddingexhibit.com/

I have never advertised this way.  Anyone have any suggestions?

Should I set up the booth like a typical festival and charge guests while advertising our services for bridal henna? Or should I give small designs away and not charge for them. Or both...

Should I give away a coupon..example: $25 off, raffel off something.....

Thanks in advance for any advice or words of wisdom.
