State grant availability varies greatly; Federal grants are readily available for minority business owners. Check your local county Minority Business Enterprise (MBE) office for information specific to your county of residence and Missouri state grants. Also write your congressperson or Senator with copy of your business plan.
You should research this information in one of the many websites dedicated to help women get grants. The net is probably the best place for you to start. They have an article titled Grants for women in business.
