How dense are you? Really, are you impared in some way?
Nothing you (or anyone else replying) has said anything to disagree with my first post/question :-
I have asked Lee, however he can only answer from himself in the same way that you can only answer how you do it. This forum is a good opportunity to see how others do things, then I, you, or anyone else can adapt bits to improve things if they want.
It's an impossible, stupid question? Well where does that leave all your answers?
Anyone with an ounce of brain and business sense can see it's a perfectly reasonable question. Any information you can get on how other people provide the same service or product to the business you run can be useful. So asking for an average job duration will give a benchmark which will speed up the time taken to quote.
So you're doing part of the work for free whether you collect evening, morning or at midnight. Yet you reckon you know how to run a business? Yet again you seem to be trying to substitute arrogance for ability. Anyone who doesn't think that they can learn from others, and help themselves by asking questions and looking critically at the way they do things themselves is a tw4t.
There's a wealth of knowledge on this forum which goes far beyond flinging sh1t up a wall as fast as you can. If the majority had replied to my original question with "it always takes me/us .." and then given a number quite different to my original "I'm working on two or three days in an empty room with all the first fix done." then I'd be happy to change my opinion and do things differently.
But no one, including you, has said anything different. The job you posted showing that you'd done a decent job in a day is fine, but that kitchen is about the size of my downstairs shower room. I wouldn't even be quoting for a room that small, it's not what I/we do. So your average is a two day job, plus collecting the materials the evening before. Which is EXACTLY what I said originally, but as you're an expert at running a business you seem to think the bit you do for free the evening before changes something. It does, but not in the way you'd like as it means you're doing work for free that you could/should be getting paid for.
