I’ve had an idea for the last 15 years.

~10 bucks and a card is printed and mailed to address for you. Add a few bucks for a handwritten note.

I still think this is a good idea. I just had too many other failed ideas to put the time into it.

I'm aware of at least one business that does this already.

Which one?

I guess it depends on your definition of "handwritten"; they're actually robotically written, so no actual human hands are involved.
