There might be other community organizations that are able to help you, too. In Spokane, Wash., we have an organization called SNAP (Spokane Neighborhood Action Programs) that offers business planning and financial services to small businesses like yours.

You should also find a free networking group to help you. The one I belong to is called BNA or Business Networking Association. We only pay for our breakfast – there is no cost to attend. I'm sure there are similar organizations available in your city, whether BNA or another networking group.

And, you should join a local Rotary Club or Rotaract Club. There will be other business people willing to help you, and you will learn a lot about your community and its resources, which will help you develop your business plan.

Finally, if you care to e-mail me, I can send you a template of a business plan.

Best wishes and good luck on your venture. Hope this helps!
