I'm enquiring with small businesses about various products and services at the moment and based on what is returned as a quote, I think the thing many of them suffer from is a low level of office tools and automation. I speculate they simply can't itemise the required labour and materials from multiple suppliers into a presentable format.
Then they should give up and leave the industry to competent people that can automate. Get with the times or get out of the way.
