Government money is another possibility regarding sources of capital. Grants are available through most government organizations. This is true on a federal level, a state level and even a municipal level. While its highly unlikely that grant money would be able to fund your entire venture, these grants can help to subsidize some of the costs you will incur. Monies are available for specific areas such as research, technology, job placement and training.
Bear in mind, when applying for grants, you will be in competition with both other firms as well as grant writers. An entire industry has been created where individuals act as grant writers, in an effort to write proposals to secure government available funds. Thus, the area is highly competitive and you may need an expert to guide you through the landscape.
