Need a wider lens for interior shots!??

I just got put in charge of taking photos of a construction company's buildings for their website and catalogue, yet when doing some run throughs in a building with the owner I noticed that no matter how far back I was in some small rooms I still needed to capture more, right now I have a canon 20D with a 17-85mm AF/IS lens and I was seeing if there is a step down filter or even another lens that will capture more of these rooms, if there is anything I can get I need to know soon because I need to take more shots for them in a week, I really appreciate it!

Canon does offer the EF-S 10-22 f/3.5-4.5. That's the widest I know that Canon makes. Dunno about image quality, distortion, etc. though since I have not used it.

Sigma also makes a 10-20 f4-5.6 that's about $500. Still expensive, but less then the Canon. I have the Sigma and love it. I'm not sure how it compares to the Canon though as I've never used it.

How about photoshop and stitching two shots together? You could resize to fit the page.
