Market Research & Feasibility for an Interior Design Community/Business Website

I\'m looking forward to build a community, business, and networking website especially for interior design and related trades (interior contracting, decor, furnishing trade...). Interior designers, contractors, and suppliers will post their portfolios/ products. Someone looking to hire any of the above trades will find anything they\'re looking for on the website. Members will advertise their services and communicate with other members.
I want to know what search demand and traffic would there be for this kind of website & whether it\'s feasible to build it. Kindly note that the website mainly targets the middle eastern, north African, and Asian area. Some might consider this another directory but it\'s not, it plans to offer the member interactive features that directories don\'t. So this is the main idea. If any of this is not clear please let me know.
