Frameless Shower Enclosure: DC

I decided to post this question given the spot-on recommendations I've received so far from this forum.

We want to build a frameless glass shower enclosure for a 3'x3' shower. We want to shop around to get the best price but also want a reliable company.
Any recommendations?

By the way, if anyone needs to have their oak floors stained in black, call Classic Floors Design (202-872-9860). All I can say is that they reproduced the exact color we saw in a magazine we showed them. These guys are highly recommended (the actual person that did the floors is Richard, the guy is an artist). I cannot say the same about my contractor, who should be banned from doing any work in the continental U.S.

So, if you have any contact info worth sharing about glass companies that do good work please let me know,

River Glass is the best in the area. Not the cheapest- but the best.
