Have been working in 3D interior and exterior rendering from since I worked for an architectural firm, so I've been taught about home design, building architecture and visual issues. Also, this semester I've worked on UDK, so I know what you need for this project. Actually, I'd be charging $1,000 but the system wouldn't let me type that quantity. Also, for the videogame I'm working on along with other friends, I was the level designer, so I understand your requirements. In any case you'd like to discuss more about my idea, you can send me a PM and send me your Skype username (if you have one). Greetings, and thank you for your time!
