muffman you have it all wrong , welcome to the real world
if said lady charged
R1000.00 per hour , the rate in my opinion should be as follow
although the rate is per hour , it takes an hour and a half , from start of one booking to start of next, half hour is reserved to grab a quick bite, freshen up and allow previous client to vacate safely so a direct translation of time VS cash would be
R8000.00 for the required 12 hrs , then most lasdies will not have a 100% occupancy , they need to set the figure here , I would guess it would be around the 60% mark for ave WG , IE she will have 10 available slots a day and only fill 5 a day on ave per week
this calculates out to
R2400.00 per allnighter
but then again its willing buyer willing seller deal
