lol - Now we are talking!
When I price I price on contracts to 'stand alone' - without ancillary and janitorial - if I get it great, if not fine, (I was refering to supervision and janitorial delivery above not as part of the essential contract). Having said that I also quote bearing in mind overall running costs, therefore I can cost slightly less as my Company has a high turnover and to run a contract like that mentioned would not increase any overheads other than the basic wages and the small cost of materials. (before it's asked yes I have quoted like that from the beginning as I knew I was going to build a reasonable sized business).
I do have a basic costing sheet, much like anyone else in this industry would have and work on employers NI, P&EL, plant & machinery, materials, uniform etc and the results are based on the wages and hours required for the clean.
Yes we are all in it for different reasons, mine are not far off yours but I expect to be in it on a longer term than you and take a decent income along the way!
