First, you must see yourself for what you really are - a for-profit business. You need a business plan, a marketing plan and a plan for short-term capitalization to expand your capacity and facilitate growth. There are very limited philanthropic dollars available for you.
However, here are some sources of financial resources, advice and information that may be more appropriate to your business needs: your local Chamber of Commerce and/or business association; a dean or professor in the business administration department of a local university, particularly at the graduate level; local banks and/or local branches of national and international banks - seeking creative small business assistance in the form of low interest loans and possibly some community reinvestment grant/loan packages, depending on the financial institution and the constituent demographics of the service area.
