need some help picking out a keyboard

Hi guys, I'm looking to switch from a Zoom65 EE to an ergo keyboard. I have a feeling a product with my needs doesn't exist and I'd have to go custom...

• split kb
• wireless to PC (wireless between keyboard halves a plus but not necessary)
• 2.5ghz dongle would be sweet but not necessary
• switch hotswap
• led lighting (doesn't have to be per key)
• variable tenting
• travel case?

I'm located in the US. My budget can go up to $350.
