Zen Cart Meta Tags Modification

My website is located at http://www.mdsoptics.com. Looking for Zen Cart expert programmers. I want a modification made to the product page metatags.

On the meta title I want it so that it is the product name and the dash and a space followed by the text "SALE Online".

Here is an example page: [login to view URL] If you know Zen Cart it shouldn't be too complicated for you and you should be able to do it in under an hour.
