Good ole' dcs08! Complete rant off the subject. The original post is about using a quotation form to distinguish between a professional and non-professional service.
But talking vans/cars:-
Up until the end of 2006 I used a J reg Honda estate with 200L in the back but still had an industrial uniform jacket and would even use a collar and clip on tie with it when canvassing small commercials.
DCS08 - My parents wouldn't have things on credit and generally I agree except when I find I can lease/purchase a new van, reduce fuel bills by half and reduce down days to virtually zero. This ameliorates the obvious cost of depreciation.
When you're ready, get a van and pass the car to Mrs. and baby!
I've started using quotation forms in the last month and mainly use them for medium to large domestic customers (that's £25/£50 in my book).
I use them to specify frequency - e.g. prices for:-
Monthly, two-monthly and one-off.
Price for initial clean.
Condition and cleanliness of their windows to start (Good, fair, poor)
A space for special conditions such as:-
Includes conservatory side glass but not roof or
Doesn't include inaccessible window over barn conversion and car port
Putty loose in some windows which we will not be responsible for
