RF circuit designer

I need a circuit that transmitt on the 27Mhz Band, multichannel that i can select different channels by soldering som 0Ohm resistors, with an output power of 4w and that should work from 9.5Volts to 14Volts outputting same power on all of them, at the bottom of the circuit i need a PTT pad, Power supply Pad, Grond Pad and RXD Pad, one of the most important requirements is that the harmonics must be under -60dB from the main carrier. I attach the size of the transmission board.
