Carolyn,
I think it depends on what line of business you want to get into and what State you are in.
My friend and I are starting a new business, Small Business Administration has not been very successful, it is almost impossible to get funding through them at this point.
Whatever you look for you will need a business plan that a potential investor can evaluate the risks and potential gains. You will also have to have some sort of 30-second "elevator speech" to put in a few words what your business is about and what you can offer.
You may want to check out Entrepreneur Magazine, they have very good information on almost any line of small (or big) business you can get into. In our case, we are starting a pet food and pet supplies business and I ordered their "manual" with information and resources, it was invaluable information. It's kind of expensive, $ 69 for the binder but it was well worth it. Here is the link

I also got their book "How to start a small business in Arizona" (which is were we are at) but you can find it on Amazon.com for every state.
You can get lots of information as to how to get financing on

You will also find great information through the National Association of Women Business Owners
www.nawbo.org
Private investors through networking is a great opportunity, we actually had someone approach us who was willing to bankroll us for 7 years, it hasn't worked out for several reasons, the main one being that he wanted us to go "too commercial" and wanted to have a 51 % stake in the business for those years, which I wouldn't have a problem with but 51 % also means he could overwrite any of our other business decisions.
In general it is good to find an investor, aside from networking, you can find them through Angel Investor Networks. In Arizona it is
www.edesertangels.com and
www.arizonaangels.com, I am sure you can find information or referrals on their websites, otherwise just find a chapter in your state.
I don't want to make this too long, in my previous career I have written 100+ business plans for small and medium size companies, so I know what investors are looking for. If you need more info, just email me directly. Otherwise there are really good books out there giving you instructions on how to write a business plan. If you don't have a compelling business plan you won't get any financing through banks, SBA (Small Business Administration) or investors.
And truth being told, without a business plan, I wouldn't take out a personal loan either. You need to do some research, get organized, make financial projections, etc. before you spend your own money or anyone elses money. Aside from that, if you are not careful you can not only blow your own personal money but also can have creditors going after you personal assets.
How exciting though. Whatever you do, I am sure you will succeed!!!
