You want Let's Encrypt.  They don't charge for their certs, and their
CA is widely accepted.  A recept paper says they're now the #3 CA
by number of active certs.

There are a bunch of different open source clients for LE.  I use
a cute little shell script called acme.sh for the web and mail certs 
on my fbsd system.  The certs have to be renewed every 3 months so
you definitely want to set it up so it can renew automatically.
