Have you become involved with any Chambers to meet people and develop their trust? That is one of the best methods of networking and gaining the crucial trust without dealing with the upsell nonsense of BNI. Being involved with Chambers has helped me A LOT, particularly as I started focusing on moving into Michigan.
You never said where in California you're located. Regardless, your clients are going to be within a certain radius of your location so get out and be seen, too. The more people see you, the likelier they are to remember you. I think the rule of thumb is someone needs to see you and hear your name like 7-8 times before they even remember you. Get out, be present, be seen, engage in discussions (even when you do not want to chat), do not be a hard seller but make it clear what you do and your ideal clients. I now walk down the street and into various businesses in Michigan, for example, and people know who I am, or they've seen me enough that their curiosity makes them stop me and ask questions. All of my growth is organic, it is controlled, and it is manageable.
The owner of a firm called me yesterday asking if I wanted to buy his entire company. It is just too large of a purchase and with the state of the profession, I think you are better off spending money on effort than a book of business where you WILL inevitably lose some of those clients. And no seller really wants to tie payout to retention because they have on idea how you will be for their clients. In 2021, I did attempt to buy a smaller firm--about $350k gross--and we could not agree on terms. A larger but still small firm came in, quickly bought up the practice, did little due diligence, and it has proven to be a disaster--they did not communicate anything to clients, many clients were not extended last year, and they have lost a ton of clients (and I have gained some of them).
A while back, yes, buying a practice would be a great way to jumpstart things. Since COVID, though, and aging out of practitioners, my opinion is spend that $35k in networking and building trust. Call financial advisors, lawyers, bank managers, etc., as they are all excellent (generally speaking) sources of referrals. Take them to lunch or for a drink or two after work.
Others have said it, I will repeat it--when you are starting out, you will want to accept basically any client that comes your way. Don't. Identify your ideal client and stick to it, otherwise you will end up at capacity with lousy clients and you will end up shedding them and effectively starting over. As JAD stated, never compete on price. Compete on what you can do for the client in an efficient manner.
