As a mobile detailer myself, i agree with the pricing variations for the size and i'd seriously reconsider the inter. & full detail prices....assuming 15 cars for clay bar and 6-8 oz (usual touch up for my regular 2-3 wk clients) of ds and everything else and buttery you are losing $40-60 per car what is your hourly rate (i personally start at $20/hr - touch up and minor corrections. Full corrections and show jobs up to $30 /hr)
Just another detailer helping others like so many have done for me.... First Class Mobile Shine
