Hey im starting a business and i need to know how do i apply for a small business government grant?

Im starting my business and i need money to start. I have been on numerous sites that want you to pay out alot of money just to give you info on government grants. But i didn research and i found that like 75% of those sites are scams. I want to be able to apply for them myself but i don't know who i am suppose to talk to....i live in south carolina.
