In my never to be humble opinion.
(A) I would stick with only 2 fonts. One for your heading (business name) and that one can be creative, wacky, bold, ect.. Second font for the other info.
(B) For other info font pick a clear, crisp, clean font, not one that will cross your reader's eyes.
(C) Too wordy, try this: "ask about our protection packages"
(D) Also, just come up with one "catch phrase" maybe 2 lines long max.
(E) your name & contact info at the very bottom of the card
COMPANY NAME
CATCH PHRASE
PROTECTION PCKG
CONTACT INFO
CONTACT INFO
Here's another idea. I'm sure you would like to highlight the packages you have (winterizing, after winter ect) so why not put all that on a flyer? You'll have plenty of room to list your various packages and detailing info. and you can simply staple your biz card to that flyer.
Hope I was able to help.
