Obtain vinyl lyric for etching

I would like to create an etching on a window (about 2'x4') of lyrics from a nursery song. It would be nice to incorporate some simple graphics to enhance this etching. Anyone know where I can go to get this designed and/or cut out of vinyl so I can attach to the glass and apply an etching compound?

I've seen many web sites that have graphics and others that have letters but none that lets you create something (like a computer file) and use as a template.

While I don't have one, it sounds like something a Cricut could do. There are several font styles and sizes to choose from. Since the window is so large, the stencil letters may need to be cut in rows or sections. Of course the vinyl does not need to cover the entire window, just the area for the lettering and graphics. I don't know what kind of vinyl to use or where you'd have this done (unless you have your own machine), but I'm sure someone here will chime in.
