Magnetic Stickers for a car

[WTD]

If anyone makes these, I'm looking to get a single car sticker made, simple black text on a white magnetic sticker thing.

Please contact me through my profile with costs! Many thanks,
Steve

It's OK it's for a joke for a mate, I'm sure when he realises it's stuck on his motor, it will go walkies, very fast in my direction
