High net-worth investors and lenders will want to be comfortable that this new business has all of these elements (except maybe the capital part) in place before they write you a check for x amount of dollars.
In terms of your options for seeking financing, there are two types to think about.
Option 1: Seek Strategic Financial Investors
This can be an option worth exploring if you can find an investor (i.e. angel investor) or group of investors (i.e. venture capital fund) that are interested. In this instance, you will be giving up some equity but these financial investors are generally very helpful.
They offer industry expertise and a strong network of contacts which will allow you to grow internally as well as having the opportunity to form strategic partnerships with larger companies. Keep in mind that it can be very difficult to obtain financing from these investors but if you succeed, it can be very helpful.
Option 2: Seek Financing Options with Banks
You may have to go to several regional and community banks to find a lender with favorable terms but it is an option worth exploring. The Small Business Administration also sometimes offers attractive opportunities to obtain financing.
In working with the bank, be as forthcoming as possible regarding your history and your needs. Your banker, in turn, will tell you exactly the information he or she needs to present your "best case" to the bank's credit committee. If possible, use your past success or strengths as a way to market yourself which will help give the bank assurance.
Good luck with the venture and keep us posted on how it goes.
