If Foo Corporation is a private corporation whose 1,000 shares are owned (50/50) by two people, how is the value calculated?

Example 1: Foo Corporation has existed for 4 years, but it has yet to be profitable and owns $3,500 in assets. What is the value of 1 share?

Example 2: Foo Corporation is 6 years old, has negligible assets–but 120 loyal customers, and is running an annual net loss. What is the value of 1 share?

EXPLANATION: The owners of this hypothetical business are currently operating as sole proprietors. They are both eligible for financial assistance (e.g., Medicaid, food stamps) based on their net income level, but the programs flatly reject them because of their significantly inflated (~5:1) gross income. By starting a C Corporation, I believe that they would be able to bypass this bureaucratic red tape. The question is whether or not their 50% stake in the C Corp’s stock would itself disqualify them from the programs as an asset. Note: The business has negligible assets (customers, an old truck and some equipment). How would they formulate the value of their stock for official (e.g. food stamps) purposes?
