No one can answer that but you. There is a vast difference between businesses. For example, a service business takes much less capital investment than a manufacturing firm. It is up to you to develop the plan for your business which determines cost and other investments. There are numerous ways to finance a business including personal savings, loans from relatives or friends, traditional loans, government loans, venture capital, etc.
Most government loans are in the form of guarantees through local banks.
In most cases a loan will require collateral and a convincing business plan. Government grants are rare and only available for limited, specific enterprises. Contact your local Small Business Development Center for more information. You are responsible for all the required licenses and permits regardless of size. Typically, as a small business owner you will be responsible for everything, from marketing to maintenance.
