drilling your own mounting holes

has anyone ever done this? or is it even a realistic possibility? im not seriously considering trying to do this myself, but i was thinking of mayb taking my board to a workshop somewhere and seeing if they could drill a custom mounting hole, cuz my stance got all messed up from the new LF plates... if anyone has tried this, or knows anyone who has, or knows where i could do this, your insight would be greatly appreciated so i dont ruin my board by doing something stupid!
