Where to sell high margin, six figure rev business growing 20-30% YoY?

This business has a perfect domain for its industry (think onions.com for an onion seller) and is outgrowing the underlying 4B USD industry by a 4-5x rate, while maintaining 40-50% margins. The product is a physical good and the business has maintained high sales despite the current macroeconomic situation.

Founder is interested in selling but mainly for liquidity reasons - they would love to stay on and keep growing the firm.

Any suggestions for sites (we’ve tried the basic ones like MicroAcquire) where we could sell to someone who has experience in e-commerce or startups more broadly?
