Yes, if you can afford it. An intermediary can search web sites for businesses matching your criteria. They can also search for “pre-market” businesses by putting together a list of possible sellers and contacting them on your behalf. And they can reach out to other intermediaries about “unlisted” businesses.
An intermediary can also do a lot of the initial due diligence and vetting for you, which will save you time. And they provide confidentiality. Your name won’t be disclosed to sellers until you choose to disclose it.
The main negative is cost: you’ll have to pay the intermediary a non-refundable retainer (usually a one-time fee of $50,000 or more or a monthly fee of $5,000 per month or more) and a commission on each successful transaction ($150,000 to $300,000 on a $5 million transaction). Fortunately, the retainer is deductible from the commission.
