just for a rough price point, my red IKPs are from back when Cjanik did them in 2010. i think price point-wise it was around $200, but he gave up b/c it was a royal pain in the arse to do without damaging the plates.
it actually might be in best interests to do a custom cutout! so you can just pry it open and not worry about anything because you'll be replacing with a new piece anyway.
