15-30 sec theme song with lyrics

I'd like to commission a theme song for a YouTube show I am working on. The basic premise of the show is something like if Morticia Addams took over the neighborhood after Mr. Rodgers retired. So, dark and spooky (but wholesome) fun. I'm open to ideas for the theme song, but the style inspirations I currently have in mind are things like the Goosebumps show theme, any song from Nightmare Before Christmas, or even something like Cab Calloway in the original Betty Boop shorts. Something cartoony, but juuuust haunting enough that it might give any 5-year-olds that hear it nightmares.

I'm looking for something somewhere in the range of 15-30 seconds, with lyrics. Vocals not required, I can add my own.
