I would bring forward your vaccination and heath check.
Most puppies need a health check within the first few days just in case the vet finds anything - the breeder will then take them back. leaving it to the 24th Nov is complicated for all sorts of reasons but not least because it gives you limited come back to the breeder if something is wrong.
If he doesn't go for his vaccines until then, then he will be missing out on vital socilisation work you should be doing out and about in the real world, right now. This increases the risk of behavioural problems when he is older.
The fact that he is getting more vocal as each night goes on suggests he is getting more distressed. He is learning that being left alone in a crate is the most miserable thing in the world. That's not what you want him to learn so you need to change his experience of the crate by making it less miserable for him. In reality that probably means sleeping beside him - either him upstairs or you camping downstairs. He needs soothing and to know he's not alone. Plus he needs letting out into the garden throughout the night - probably around 2-4 times a night but puppies do vary. Expect that kind of routine to go on for about 4-8 weeks.
He is likely to be deeply distressed by being left alone in the house/crate for the hours you suggest when you go back to work. You need a better solution, unfortunately. It's not just a case of saying 'he'll take longer to housetrain'. It's the risk of deep and serious behavioural issues that should be your biggest concern. Some puppies cope with being left when they are young. Most don't and are unhappy. Some others develop full on seperation issues that reduce the chances they will EVER be able to be left happily.
Unfortunately, puppies need what they need. It's not much good explaining to a puppy that you need to work - they didn't choose to live with you, you chose them. It's you that has to provide what they need, not them that has to behave how you need them to.
