There are some legitimate business opportunity packages out there, but honestly, they are few and far between. In most cases, you are better off crafting your very own business opportunity rather than trying to find a business opportunity that is prepackaged, turnkey and ready to go. A turnkey business opportunity is one that provides you everything you need to get started in business in a start-up package for a flat start-up fee, or at least claims to. Some of them have ongoing membership fees as well.
Of course, there are some companies that offer true turn-key opportunities like distributorships or pyramid plans where you sell their products for them, usually through party plans, and recruit other representatives for a percentage of fees. You may find a business like this appealing because it is a package deal that is easy to start-up and generally has good support through the company and an up-line.
The legitimate businesses of this nature are well-known - Avon®, Home Interiors®, Herbalife®, Tupperware®, and Mary Kay®, for instance. You really can make money in these types of businesses while maintaining control over your own work schedule if you are willing to give it your all. However, some people just aren't outgoing enough to make a distributorship business work because they don't have the personality for direct sales and recruiting.
