From openhardware you can download the Gerber files and have them printed from your favorite pcb factory. As you may have noticed the pcbs supporting rfm69 do usually have a pro mini 3.3v socket. For nrf24 you still can't use lipo batteries without a ldo voltage regulator. Personally I'd prefer the rfm69 as you can choose the frequency you prefer while the nrf24 are stuck to the heavily crowded 2.4Ghz
