Well, we're far apart, I'm in Idaho, not ideal.
Here's what I'd be willing to do; If you can make accurate templates (patterns) for the grills you want I can make them and send to you. You'd be on your own for making the patterns and subsequent installation, I can put whatever attaching hardware you fancy on grills.
In all honesty, I think you'd be better served by approaching a local shop to do this for you...it's not difficult work for a decent cabinetmaker.
