I 100%+ agree..... You will need a lots of dollars ($500+ USD probaly) to
get a multilayer board done (8 layers probably) .
Why dont you purchase a development kit first and get experience with known
working hardware and profesional software.
I know million dollar companies that would steer away from such complex
designs, as in their experince..... they can see trouble coming!

As a much simpler alternative, buy an eval board for the processor and
interface your parts to that. You stand at least a reasonable chance of
success if you get big important pieces pre-done and running out of the box.
