I had trouble finding brokers who would take me seriously. I wanted a rare antique vessel, plus I'm a woman. I'd usually get interest via email when I inquired, but once they spoke to me, everything went quiet. Even when I showed up to look at a boat, they'd pepper me with questions and actually tried to talk me out of buying an antique. Granted, wooden boats are cheaper than the boats you are looking at, but still -- most of these brokers only dealt with woodies, so it made no sense to me. I couldn't help but to think that I was negatively judged.
But I never gave up and you shouldn't either. My first broker only showed me his listings, so I left him. The other broker spent all of his time telling me I'm making a huge mistake in buying a wooden boat...
After that, I just found boats on line (through Yachtworld, etc.), and then I'd schedule an appointment with the seller's broker. Since they already had a vested interest in selling the boat, they were willing to show me the boat even though I didn't have a broker representing me. It worked out for me that way.
What's cool about doing it this way is that (a) you get to see a lot of boats, which in turn will show you what you DON'T want, and (b) when you do find the boat (it took me over a year to find her), you'll know -- and then in my case, I just used the seller's broker but hired a full survey and got advice from the surveyor on what I should offer vs. asking price.
It's not the best situation, but it keeps you looking at boats.
Go to boat shows, too -- that's a good way to see a lot of boats in person, and again, part of the process is finding the boat style that suits you. I originally thought I wanted a 40' boat, but after seeing them in person, I kept getting smaller and smaller...my boat I got is only 27' and yet she's the perfect pocket cruiser for me. But it was that determination and all the leg work I put into looking at boats through on-line sites that helped me find her. You'll find your boat, too.
