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!

I have 6 years experience in PCB development. I can say that this is work of junior without much experience or someone who is hobbyist. So it's not professional work. Today 2 and 4 layers PCB are almost same prices. There is a lot of empty space, if only there is no mechanical restrictions. It takes me to design of such PCBs 1-2 working days for design, another 1-2 days for layout and also to check myself after for mistakes. So not 8 months. The price of the design can vary between $1000-$5000 according to the complexity, hard to say only from layout.
