Who you know will help, but likely not as much as you would expect.

I want to address the importance of your personal network. Okay, it's not completely worthless (I have to write slightly incendiary titles for SEO.), but it's likely not worth as much as you think.
That's both good and bad. Let's start with the good.
When prospective searchers are first presented with the idea of buying a business, they often feel unqualified to do so. They think, "I don't have enough money to do that," or "I don't know any business owners." These doubts filter many would-be searchers out of the process.
This's a shame, because you really don't need money or connections to be a successful search fund entrepreneur. We'll talk about the money question in a different post, but here let's talk about the network.
You might know people in private equity, investment banking, accounting, law, or similar industries that have great networks of business owners and intermediaries. You may think that they have a much better chance of finding a good business to buy. Or maybe you are one of those people, and you're confident that if you just send a message out to people you know, you'll have a deal in no time.
Unfortunately for the well-connected, but fortunate for the rest of us, search fund entrepreneurs almost never buy companies through their personal networks. They all try, as well they should, and several have succeeded. However, the large majority need to search outside their inner circles, a fact which levels the playing field a bit.
So why is this? Why can't someone who, for example, has been doing PE deals for the last five years buy a business very quickly?
As a searcher, what you're looking for is not quite a needle in a haystack, but it's close. Think of all the filters through which a company must pass before you decide to buy it:
Let's say you have a powerful, intelligent, well-connected personal network of family, friends, and colleagues, and they send you, optimistically, thirty opportunities over the course of your search. What are the chances that any of those will meet all your criteria? Almost nil.
This means that, while any new searcher should alert his or her personal network and welcome any leads, almost all of the searcher's time and effort should be spent searching outside that personal network. Because there are so many ways for an opportunity to be disqualified, every searcher is obligated to fill the top of the funnel with as many high-quality leads as possible - thousands of them. And to achieve the required volume of leads, the searcher must look far and wide.
Again, you should absolutely let your network know what you're doing, and you should encourage any leads. However, manage your expectations. There is yet another filter here: your contact must actually understand what you're doing and your search criteria. Not many will.
Your family and friends might tell people you're "fundraising" or you're "in finance." And if they do understand that you're looking to buy a business, they'll send anything they come across at first - the gas station down the street, a web domain for sale, or Twitter. Then when you reject those opportunities, as delicately as possible, they'll get discouraged and stop sending you leads.
So what should you do? Create a simple e-newsletter template using an email marketing tool like MailChimp or Constant Contact, add all your personal contacts to a distribution list, and send a quarterly update that gives a very high-level answer to the question "How's it going?" Pick out 2-3 industries you've looked at, and say why you found them interesting. Tell a story or two about interesting opportunities. And provide a quick narrative about how you're feeling.
With limited time invested, this will help you in a few ways:
