Sample business plans can be found at bplan.com. Look at a number of them even if they are not exactly want you plan to start. Also SCORE a volunteer organization that help new and existing business have counselors who can sit down with you to help you with your questions. Also the on score.org you can find your local SCORE office and tools such as templates for your plan as well a tutorials on various business start up questions. Plus there is a section that speaks to financing a business. Recognize that any loan will need to be secured with collateral.
As for grant money mentioned above, unless you are a non-profit, any grant $ would come from Federal or State programs - to prepare you, there are very few grants & they are tough to get. They are mostly designed for job training, etc. See grants.gov as the one site for all Federal grants.
So please check out score.org for to access free business counseling and helpful tools.
