Needing a company that can put vinal onto aluminum blanks. Do any sign companies here in BCS have the blanks in stock?

There are several sign companies that have vinyl cutters and can apply it to a number of surfaces. Not exactly sure what kind of blanks you envision. My wife and daughter make signs for their own use on metal and wood panels they buy at craft stores like hobby lobby and michaels and use their craft vinyl cutter. I suspect lots of people besides sign companies could do this now days.
