wedding planner fees

hello,
I am doing research on the average price a couple is willing to pay a wedding planner. stats i have are 10 yrs. back. i am doing this for a small business course i am taking in my area. I would like to hear from brides fees they have paid or from wedding planners. Also, we had a discussion about diffient cultures using wedding planners/coordinators. the discussion became heated when it was implied that minorities do not use planners because of the expense. I would like to hear what others on this board think.
