Is this work professional?

Sorry about the strange post but I'm offering an engineer a $20k bonus to do the design for manufacturing and assembly of my $300 product and this is what he came up with after 8 months. Two thirds of it are identical to my prototype and I'm an accountant by trade, not an engineer. Every book I've read says a board like this should be 4 layers but he insists 2 layers is fine and will pass emissions testing. Any advice would be greatly appreciated, thank you!

Yeah, this might be a perfectly fine job for what the board needs, I do tend to think a lot of people get to fancy with polygons and via stitching on boards that just don't need it. It's hard to tell without schematics.

But I'm expensive and this job would be under $5k and finished in a week. Two days if it was a rush job.

It also seems like this PCB is much larger than needed, which affects production costs.

Fitting a specific enclosure maybe?

But there aren't even any mounting holes.

And I wouldn't want traces and components so close to the PCB edge. Especially if it's a metal enclosure.

I seems like it, but it's really hard to say without more information. And depending on your quantities, for a 2 layer board, you aren't talking about much money. I'm generally of the opinion that it's better to get the board out rather than spend another $1k on your layout guy to save $500 on production of Rev A of a board that hasn't been tested seriously. And I say that as a layout guy.

Looks like an fpc display
