The question is a bit vague. In order to determine the right approach it would help to know the general type of business you’re planning.
Do you need 100k for a neighborhood store or 30 Mill for a production facility?
Service, sales or production?
Single owner or corporation by shares?
Are you willing to share control over the new company in exchange for unsecured loan money?
Startup financing is a very broad topic. However, be aware, the current economic crunch will have you hard pressed to find a bank willing to finance even if you have impeccable credit, own seed money, and come up with a rock-solid business plan.
Regardless, some resources:
Federal Small Business Administration:

Entrepreneur.com’s business financing section:

I strongly advise against any infomercial stuff you see in late-night TV. For all I know these offerings are useless, or at best recycled information you can find free on the aforementioned sites.
