Seeking Online Biz $120-600k SDE

Hi - just joined this platform and excited to get connected with some folks here. I am on the hunt for my second acquisition. I am targeting a high-margin online biz focused on a niche problem/topic with a strong brand/following. My first acquisition was an email newsletter focused on gold & precious metals trading. Any businesses close to that description would be attractive given the synergy likelihood. Would love for folks to shoot any direct listings my way, advise on any specific brokerage sites I should be looking at, and/or recommend any SBA lenders/brokers that specialize in this kind of profile. Thanks!
