Query: a place to start

I don't like giving a poor review, but this is sort of basic, and there is nothing wrong with a basic book, but on cleaning?I mean, it is a sort of basic business, its not that its hard, its that no one wants to do it - that is the success principle of the cleaning business.I can really recommend this book on the subject, its VERY good and anyone fighting the recession will win big if they follow this one book:Mopping Up Millions!: Making A Killing In Cleaning -Get busy and make some money!
