looking for someone for party of 125

Hi all, i posted this but can't find it. i received a call for  a party she said probably 70 women would like henna, i asked if it was traditional wedding henna, she said no, they would most likely want bracelets flowers, ect. i need to call her with a price, i'm thinking 75 each minumun sp of three hours. does that sound right, i live in westland, mi it's on 15 mile rd. i can pay for gas i don't have a very reliable car. ,for January 30 at 7:00. please let me know soon she called 3 day's ago and is waiting for a price. or i will just have to let it go. Thanks so much  Diane
