OT: Interior Home Designer

Hi there, I know this is offtopic but I did a Furniture Modeler (Autocad style) application and Interior Home Designer for my final year project- I’ve graduated now and I’m interested in extending the program to be more realistic, more features etc.

My question is- what is the market like for this type of software? The most famous one I can think of is Broderbund’s 3d Home Architect, but I’m not sure who my target consumer should be, I’m thinking furniture stores and professional Interior Home Designers- my program would be more like a marketing tool for them.

What do you ppl on the forum here think? Is this a worthwhile application to develop? I’d appreciate any comments, tq.
