I know the cleaning company do both domestic and commercial cleaning. Not sure yet whether I'll be offered one or both types of job or how much there'll be. I imagine it'll probably will be the odd office or restaurant every couple of weeks or so.
(I suspect there won't be enough to justify a truck mount or even a LM system as I'd have thought the company would be doing it themselves if this were the case.)
Now that I have a few rough figures I can contact the company and appear that I know what I'm talikng about...

Out of interest I haven't really looked at LM in detail yet. Are there any systems that are superior or are they much of a muchness?
