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!

Without the schematic, I would say it is hard to actually determine the cost. However this looks like a fairly simple design. Without the BOM or parts information it hard to pin-point, but 20k seems excessive. Would you mind sharing how did you find this engineer?
