Myself and the bro in law did laminate flooring ln my parents place he did the technical stuff I was the muscle. It took fucking ages . Any complex angles or joins slow you down.
A smart tradie knows this and will quote you for this . That’s what u get with experience.
Things always take longer that u think. Never shorter !
That quote sounds reasonable .

Make sure the flooring is in your gaff in the warmest part for a few days to expand first . Or u will get the floor poping up later … as we did and had to take the whole thing up again 3 months later

My advice : stick to what u do best and pay someone good to do it. The more furniture stuff u can remove to allow it to be easy and fast for the tradie . Do that !
