   You might ask your local glass and mirror shop if they know of anyone who does front surface mirroring.

   Alternatively, There are optical companies who will re-coat the mirror, like these guys -

   One thing to consider – If the mirror is going to get coated, why not spend a little extra and have it refigured? Telescope mirrors are massed produced, dozen’s at time time on one machine. While the optics are good, they can be better. Sending the mirror off to a finishing shop, then getting it coated helps make for a better telescope.
