design a simple cable adapter PCB

I need a simple 2 layer pcbs board to take a 20 pin connector, and wire it to 2 smaller 10 pin connectors. The 20 pin connector is on one side of the board, the other 2 on on the reverse. No other electronics are on the board. I have a simple pin-to-pin wiring document. Connector 1 is a 20 pin (2x10) IDC female connector 2.54mm spacing The other 2 are 10 pin (2x5) same spacing, and female also. I would like a file prepared for sending to a service bureau to manufacture the board. Eagle Cad is preferred, but not required. wiring document is attached, and a photo of a very similar board for reference.
