Southwestern Style 2-Bedroom Casita

I'm looking for a skilled architect or designer to create a 2-bedroom casita for personal use. The style should be Southwestern with a flat roof, and the size should be between 500-700 sq ft. Due to lot limitations, the structure should be 30-32 feet north to south and 22-24 feet east to west...
