As a lightweight rider, you don't want an off-the-shelf wheel because it will be overbuilt for you.

Agreeing with Zen, Edge Composites (now Enve) makes a nice 45mm (not to deep) clincher, and I believe Psimet can get them for you and build them up to some nice hubs to make a rather light climbing set at your budget.

Also agreeing with Zen, if you want something less than 30mm deep, skip the carbon and get a nice lightweight aluminum hoop, like the Kinlin XR-270 or even XR-200. I have a 1375g set of XR-200s (28 spokes front and rear) and they're good up to about 180 lb, so you could have them built with even fewer spokes for a lighter set.
