How do I find a professional to make my product (food) so that I may do the rest?

Have you tried your chamber of commerce? I would think they'd likely be familiar with companies in your local area that may be able to meet your needs.

The following websites may also be helpful in your research:

• Salesgenie.com: Salesgenie.com is the leading provider of fast, targeted online access to the highest quality sources of business and consumer sales lead data available for sales professionals. Its database give you access to 14 million U.S. businesses and 210 million consumers and helps you profile your best customers.
• HarrisInfo.com: Harris InfoSource provides a directory of 36,0000 U.S. manufacturers available online, in electronic databases, and in print.
• ThomasNet.com: ThomasNet is a comprehensive resource for finding information on suppliers of industrial products and services in North America.
• DNB.com: Dun & Bradstreet focuses on being one of the world's leading suppliers of business information, services, and research. Its database contains statistics on more than 100 million companies in more than 200 countries.

I lifted these from the FAQ on the US Chamber of Commerce website.
