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! Joe

You stand at least a reasonable chance of success if you get big important pieces pre-done and running out of the box. Scott
