Any suggestions on the other end: where to sell a business that is both profitable and should continue to be? Asking for a friend who is looking to retire in the next couple years (at the normal retirement age).
If it's very profitable, then they might consider talking to FEInternational (or another firm like them). They take a cut, though. But they do pay referral fees, so make sure you get that cut!
Edit: Before someone says I'm crazy for saying things sell for 1x annual profit, I'm not saying that's typical for a brilliant business. It's more typical for something with heavy maintenance, or with really low profits. If you're really interested, check out the link in my bio.
