My personal advice has been offered in the book called Simple Living Investments which is in an e-book format on scribd.com.
My business financial advice is scattered through several books.
If you are starting a business there are ttwo prime sources of funding. First your credit cards or a second mortgage. You should be the first to take the risk.
Second your family and your close friends. They know how competent or incompetent you are in business. If they are willing to give you money, and I mean give, then you probably have useful business skills. They know you have a chance to turn their ‘gift’ into stock (if the time comes). If they won't ‘give’ you the money and suggest that it be loan, then make a written loan agreement and make it explicit about what happens if you fail.
Do not under any circumstances go to the SBA or any version of it. It is an incredibily corrupt waste of time. You will have to hire a scam artist to fill out your forms and by the time you get the money it will be irrelevant.
If there comes a point in your business where you have assets that have resale value, such as refrigeration, trucks, office equipment or industrial tools, that is the time that you can approach a bank for a loan on the assets or potentially a lease for some of the equipment.
Anybody who thinks that banks make loans to small businesses is using too much marijuana. Banks only lend on assets.
Lastly, if your business is successful enough for people to want to buy shares in it or buy the bulk of the business, get a reliable business consultant to act on your behalf. Mergers and acquisitions and outside business funding are treacherous areas in which only experience is what really matters. Hire that experience.
That is my advice on finance.
