Here is some info to get ya started! Will post more later.
You are running a 3 digit number, you can find guys on ebay that can print you some stylish number plates for under $20. Just make sure you mention number plate size.. some 5" tall numbers can be 8"-10" total width. You need less than 8" wide. I have used this seller a few times http://www.ebay.com/itm/2-COLOR-Custom-Racing-Number-Plate-Vinyl-Decals-Dirt-Bike-Moto-MX-ATV-MOTOCROSS-/151235031392?pt=Race_Car_Parts&vxp=mtr&hash=item23364f7160
