So here's a weird idea... erm would you do a "Hair dressing party" what I mean is, if say a group of EFrs got together on a Saturday afternoon at someones house you came round and worked your magic on all of us would you do a fix rate? Say for example 4 people all wanted a cut and blow dry? According to your calculations that would be:

80.- base
40.- per head after
so for 4 people that would be 200.- and it would cost each person 50.- plus the laugh and a giggle...
