Arduino CNC GRBL code modification needed.

hi all.. my English language is not good so please excuse me. I need to hire an arduino code writer to make some modifications to GRBL open source code to read mach3 or mach4 or any else gcode format supported by artcam 2017. because I failed to find any way to use artcam output gcode to use it with my GRBL cnc arduino mega machine. in other words GRBL gcode format not supported by artcam 2017 so I need to solve that problem because I am very good designer in artcam so I need to solve this problem . some body told me to post a thread here in this forum asking for some one who can modify GRBL code to understand gcode files generated by artcam.. thanks and regards to all of you guys
