It is true that there are few jobs here that you can just buy and turn-key into profit but if that's what you are interested in you should be looking at franchises, not this. This book is about turning a hobby into a business and what hobbies, that you may already have would be profitable. Here are some examples, if you like antiques perhaps an antiques dealer or an auctioneer is a good job you should consider? I have dogs and have been interested in becoming more professional and it';s true she did mention Dog Breeding but I was surprised that she did not mention "designer" dogs where the real money is these days. She seems to be in the ballpark but not making homeruns (hence the 4stars).
I have always recommended to a friend of mine who keeps his car immaculately, that auto detailing was something to consider, and it was true it was here with qualifications, strong eye for detail,typical fees $100-500 per job depending of course on type of car and area, qualifications, a flair for the artistic, equipment needed? Polish, rags, brushes, toothbrushes, paint. Hidden costs? Larger buildings i.e. garage to house the car while you are working. Staff is not required, which is great starting out. And of course the keys to success? Well you work at your pace and during the hours you choose, creativity is the key to keeping the competition at bay and mobile work may be something that will grow (which I think is a great idea, for those of us who can't drive to the Detailing Garage and you work is different every day. Oh yeah, how to advertise? AUto publications, body and car shops, garages, delearships and regioanl coupon books as well as car washes.
I don't know why the other reviews were so negative. I think saying it was obvious is really a cop-out. SOmetimes the obvious needs to be told, otherwise we ignore it.
