Modern Residential Architectural Designer Needed

I'm in need of a skilled architect or architectural designer who's particularly adept at designing modern residential spaces. The project involves creating a medium-sized living space, which consists of 3-4 bedrooms.

Key requirements include:
- A strong portfolio of modern residential design work
- Proficiency in architectural software (AutoCAD, SketchUp, etc)
- Good understanding of residential construction and building codes
- Ability to incorporate sustainable design elements is a plus
