Greg Ellwood is a business broker who helps value businesses for sale accurately. He charges sellers a $1,500 upfront fee and 10% of the sale price. He helps negotiate sales that typically get sellers 15-17% more than selling without a broker. During due diligence, buyers have 30-45 days to review all financial records to verify the business is as described. Lawyers then handle creating sale documents and transferring money between buyer and seller. Ellwood advises sellers to keep operating the business at full capacity until it is sold.
