mrstaylormade's Black wedding

Im at a cross roads with what exactly I should do about my hair stylist for the day of. I met with the girl who (for now) may be doing my hair and the bridal parties hair. However, when I met with her, she quoted me a price that is way out of my range ($650). I was just curious, what do you think is a reasonable price for hair? Because I definitely need to shop around. All I want her to do is style on the day of; no cuts, washes, or additional things (weaves, etc.) required. I have 7 people that need to get their hair done for the day...and Im thinking $40 bucks a head.
