Looks nice
Depending on the size & how you print it or get it plotted on a machine die-cut style (i think that is the correct term, you might need to clean it up a little) A clean & simple design will make it easier for the plotter to cut & less chance of tearing it during lifting & application.
What have you designed it in?
Oh like Guy said you will need it in an EPS or AI format
If you have a plotter then sorry for teaching you to suck eggs
