Green, yellow, blue, black

I like block letters, almost in a comic book or cartoon type theme (but not an absolute)? Think POW and SHAZAAM type lettering. I had an idea for a stethoscope with the earpieces and the end piece being dollar signs $$. Perhaps the main part of the stethoscope could be to the left of the Deals for Docs block lettering and the rest of the stethoscope swirl underneath the letters? I do like circle logos but that's not a requirement. I like green for money, yellow for some flair, and medium blue and black as well for colors. Please help with some design ideas incorporating, money, shopping, doctor theme, etc. Note: the Cadaceus symbol is NOT for doctors so do not use that.
