Need An Updated 2014 Booking Prices List For Rappers

Does anybody have an update booking price sheet for hip-hop artists?  I am starting a concert promotion company, and need to see what rappers are within our budget. I know that you really can’t get exact numbers with the prices changing constantly but wanted to get a sheet with some broad prices. If it can be broken down from 80k-100k, 60-70k, $50-60,000, and so forth. Much appreciated.
