I've been in business for myself since 1985 and still I am not a millionaire. One of the most important lessons I learned in regular assessment of small business is how to have a little patience every day of my life.
Most small businesses struggle cash flow problems.
It is not that the business itself is not a good business, but that it suffers from poor management of cash flow. Let the baby grow at a healthy pace first. First and foremost is the stability of the existing business structure. That sounds very good for the bank. You obligated all accounts receiveable, assets, inventory, future income tax refunds, etc. to collateralize that SBA loan upon receipt of initial funding.
