Spreader Ezee Flow logo for Drop Spreader

[bushhog bob]

Just bought an 8 foot EZEE FLOW drop spreader. Going to sandblast and paint it. Went to a sign company to have a couple of vinyl decals made and they said they needed a real clean copy of the logo. I found a small copy on the internet, but they said when it is blown up to a large size, that the edges would be real rough. Does anyone know where I can get a good clean copy of this artwork. They told me that digital would be even better. Thanks for any help you can give me.
