Where to begin in starting a small business for selling sandwiches without buying a place?

I am a young entrepreneur who wants to start a business selling high quality sandwiches. However to start my business, I don't want to have a shop or store, I want to sell my sandwiches to corporations and businesses...for example, they would call in and order a certain amount of sandwiches and i would make them and deliver it...simple right? Where do i begin? what paperwork do i need? what legalities might i face? What kind of funds am i looking at? How do you think i should approach this idea? I have a burning desire and will succeed, i just need a kick start. Thanks and much aloha from hawaii.

I would begin by buying either "starting a resteraunt" for dummies or "Owning a small buisness" for dummies, one option
for your particular situation is to open a sandwhich stand somewhere popular to visit like downtown or near a shopping mall or even in a shopping mall, there are legal issues you have to settle and you have to get your name out there either by directory advertising (advertising in the yellow or white pages) or spreading pamphlets at coffeeshops and other nuteral locations, the hardest part though is going to be finding out who you buy your products from and who you are marketing to, you cannot market to people in a hurry because they require premade food and you plan on selling fresh, if you want corporations buying for small luncheons your going to require a specific amount of time they have to call a head of time so that you can fill the order in time if its a big one. Good Luck

I would start researching the legal questions first. Anyone serving food to the public is regulated by the FDA. That's a good place to start. You may have to be licensed to sell food. Check with your local municipality.
After that put together a menu.
Knock on doors.
Get insurance.

Normally any business selling food items gets regulated by their respective state department of health or agriculture. However as a starting point you may want to get in touch with your local office of the US Small Business Administration. They have great resources to answer the questions you are asking for free.
