Interior designer

I'm looking for an experienced interior designer to completely remodel my house. I have a preferred style that I'm looking for, but am open to suggestions if you think something will suit the overall look better. Ideally I would like the project to be completed in more than 6 weeks, so that I have lots of time to make decisions and adjust the plans.
Project location Mumbai INDIA. Have to be available at site. Also need end to end solutions.
