Broker or no Broker?

Hi all - I am new here and this is my first post. Not sure how this forum works exactly but thought I'd give it a try with a question I have. I have recently started working with a broker to locate a business to buy. After about 4-5 weeks, I've only seen one deal come to me and so I asked the broker why so little deal flow and is this normal. They said yes this was normal, and the reasons given were: 1) Q1 is typically slow b/c businesses are filing taxes and want to wait until returns complete to list business so that valuation is more accurate (I can get on board with this reason); and 2) because brokers don't like working with other brokers, i.e. they would prefer to deal directly with the buyer and so my broker is struggling to get NDAs, etc. Apparently they don't trust each other and would rather deal directly with the buyer. To test this theory, I sent a request for more info on a business I saw listed in BizBuySell and within 4 hours I had a signed NDA...so all this begs the question, should I be working with a broker or is it actually hurting me / restricting deal flow? My initial reason for wanting to work with a broker was b/c this is my first time buying a small business on my own and therefore I would benefit from professional guidance and help from a broker, but maybe this is hurting me? Maybe I can lean on a forum like this instead? I'd appreciate any thoughts you guys may have!
