Start up hardware company using AMD processors

Hi,

 

 

I wish to design and manufacture my own motherboards for AMD Epyc Processors.

 

I also wish to design a co-processor to sit on the Infinity Fabric interconnect (based on Synopsys CCIX?).

 

Where do I start?  What department of AMD do I approach? What support can AMD give a start up based in England, UK?

 

I look forward to hearing from anyone that can start to point me in the right direction.

 

Many thanks, David.
