So, rather than looking around for an existing plan and then designing your own plan along the same lines, it would be a better idea to use software that allows you to create your own template.
The planning wizard makes it a snap to get started since you simply answer yes or no questions to create your custom business plan framework. Bplans.com offers free business plan samples and how-to articles as well as a wealth of other information. It is definitely worth taking the time to checkout. Microsoft Office Online Templates also has a variety of free templates to use with their products. The wizard indicates the information you need and you fill it in as you go.
The best place to find web templates is to search on the Internet. There are many sites to search templates and they frequently provide good supplementary details and technical support. You can regularly see a sample of the template you are taking into consideration.
Besides, your friends may be 100% behind you in your new venture, but, in case you are hoping to involve others who have actual money to invest, you may need to be able to make a convincing case. Wouldn't it be nice to have anticipated possible questions and be ready with plausible answers? If you are risking your own money, that is perhaps even a stronger reason to do some indispensable planning.
