I think what you want is a road bike, my man. Something that lets you get down on the handlebars, lower your head, and generate some speed. In your price range, look at the Giant OCR3 (about $650) or OCR2 (about $850). Both have nice, light aluminum frames and a good quality mix of components (the OCR2's are a little better, hence the higher price). Both are fast bikes, but have triple chainrings for more relaxed riding when you hit a big hill. Fit either with a luggage rack and you can change into your work clothes at the office.
The alternative is to get a true touring bike, not so fast on the road, but still faster than a hybrid and suitable for commuting or light touring. A good choice is the Bianchi Eros. At $1,000, it may be a touch expensive, but it's the time of year when you can get good deals as bike shops unload inventory. So, if you find one, make them an offer.
