My favorite out of your designs is entry
#2, except for the dollar sign. Also, think about space constraints for our signage> we may have to stack "Cash" and "Today" on top of each other. Think if Cash and Today are two feet tall then Pawn could be four feet tall. Probably want PAWN to be all capitals. A couple companies that I think do a good job with store design and thus signage are Amscot Financial and CarMax. Hope this helps. Good Luck!!!
