I also own a multimillion dollar business, and am at the very last stages of selling it, OR... having the deal blow up.
Unfortunately, there are certain realities that may be surprising to some people:
A business that produces revenue of under $5M, is very difficult to sell. It's not within the range that can justify a broker's fee, so you're on your own. For an acquirer, it doesn't increase their revenue significantly, and doesn't put them in a different category size business. It also represents a very small business that is very risky for many reasons.
Also, in terms of valuation, at that level, it will be set at 1.5-4x EBITDA. In a product-based business, that might only be 5-8% of revenue on average. In other words, not very much money.
I'm really sorry to tell you things you probably don't want to hear. After all, you've achieved a lot with your business and invested much time and effort. But when putting a business up for sale, it's judged in very absolute terms.
What to do?
Keep on running your business and grow it. Add more salespeople, watch your margins, and grow it past the $5M mark. If you can get into the $10M range, even better. At that point, a broker will have incentive to shop your business around, and can even arrange for financing for the buyer.
Meanwhile, though, you're the master of your own destiny. You don't need to report to anyone and, hopefully, you're making more money than in a typical job. Enjoy it!
