I am looking for funny Holiday cards for our business.  We will need
to find a service that has the cards and will print them for us,
complete with envelopes and such.  We would also like them to be
fairly humorous and contemporary.  Something referencing "Borat" or
"Flava-flave" ...

Hello annikeez,

Thank you for your question.

I have found a company that will do this for you.

You can supply your own artwork and they will print it for you.
However, using Borat or Flava-flav may be difficult as they are
copyrighted works.

If you need any additional clarification, let me know and I'll be glad
to assist you.
