i'm with steve on this one
once you take running costs out theres not much left.
yeah yeah its better than nothing at all, but a lot in the chapter will then expect the same price and be put off purely because you can't give them the same price,
"you did hers for that much, why not mine" blah blah blah
i don't like to change my prices, i have regulars and if they got wind of this they wouldn't be happy.
i do occassionally quote over the phone, small job or to far type ones.
but overall, i lke to see what i'm cleaning before i clean it, and explain this in detail to the custy to convince them they need an on site quote. by time ive finished the phone call they wouldn't want a quote over the phone

derek
ps.. the job was from a bni type referal wasn't it?
