If you are only making one and don't plan on trying to sell copies later on I would cut it by hand.
Lay the center down, set the gap with some fineline or scrap vinyl.
Cut down some material to the width of the out side stripe - long enough to make the trip from the front around the scoop and back again - lay it by hand along the guide.
Trim the front and collect the cash.
Should take very little time - even less if you have done something similar before.
