Small Residential Building Architectural Plan

I'm in urgent need of an experienced architect to help me create a detailed autocad plan for a small residential building.

Requirements:
- Expertise in architectural design and knowledge of residential building codes
- Proficiency in autocad, with a portfolio that showcases previous residential building designs
- Ability to work quickly with precision, as I need the plan completed in 3 days.

The plan should feature:
- A small, yet functional layout for the entire building within the given sq footage
- Specifically, an open floor plan

I look forward to working with someone who can deliver quality work within the tight timeframe.
