Honestly, a lot of perfectly good trades would run away from that list of demands or just provide a really high quote to either make you go elsewhere or cover what they would see as the high risk of you demanding more when the bill's due.
It's tricky - I'm of the mindset that I find out about a subject and want to understand what's involved. But I often bite my tongue and play the dumb homeowner rather than being the smartarse who's going to tell them how to do their job.
Having said that, I did ask someone if the underground tank they were quoting to fit would be installed according to the manufacturer's spec, fully encased in concrete. He had a tantrum, said he'd been doing it for x years, I didn't know what I was on about bla bla bla. I was very glad for him to storm off in a huff.
Just ask them what they'll be doing and how, then quietly compare this to decide who to go with.
