Can anyone recommend somewhere to get an ally footrest manufactured? 5 or 6mm plate, 10 inches by 11 inches with 15 rows by 16 columns of 8mm holes?

Just had a nightmare cutting a plate down by hand, squaring it off, marking and centre punching over 240 points (ears still ringing) and then the fecking drill goes off centre on the first hole. Had enough of that lark.
