SEO and URL Rewrite is it possible?

Hi guys,

I have gmap installed on my site tgasupersoil.com/
The site is live and you can see what I mean at it.

I need it to look better, a location page with a URL like below is not good looking for sharing. Even the link to the map from the main menu needs to be rewritten.

I use Joomla 2.5 and have SH404sef

Any ideas?

THANKS!
Pete
