Query: lightweight introduction

I agree with other reviewers, this is a handy little book if you've never been in business before and want a general introduction.However, given the title, it's logical that most people who buy this book are not looking for a guide to small business generally, but want the lowdown on how to run a concierge service. Unfortunately, Katharine doesn't give much away. I can't help feeling that this is deliberate - if you really want to know how to run a concierge service, she wants you to use her consultancy services.If you are serious about going into business, you will need a lot more information than is contained in this book, and you probably don't have a bottomless budget. Get yourself a good book about starting and running a business (Amazon.com has several) and a good book about concierge work, and you can save yourself the money on this one.
