So any ideas or is it most likely a proprietary font?

Please tell me "Signature" is a font.
Suddenly I've been pegged at work as 'the guy who traces logos'

This was the highest resolution I could find (they sent us some shitty looking jpg)

Here's some more glyphs: http://www.abetterbagofgroceries.com/wp-content/uploads/2010/06/Cupcake-ingredients.jpg

Maybe. I figured the R was custom and the apostrophe too I guess, but even the "yan" in Belwe isn't really all that close. http://www.fontshop.com/fonts/singles/bitstream/belwe_bold_ot/&s=c?&fg=000000&bg=ffffff&sample_size=96&sample_text=yan&ft=liga&acs_pt=32

.

Just "Ryan's"

Oh man, thank you so much!
Too bad it's a Mac only font.
