Design my house floor according to vastu

As a homeowner with a large house, I am looking for someone who can handle the design of my flooring according to vastu shastra. My house size is more than 1500 sq. feet, so I need an experienced designer with knowledge of Indian architecture. I'm not looking for any landscape designing, however, I would love to get advice on a colour scheme that follows Vastu principals. If you are confident in your abilities and have experience with vastu-based designs, I'd love to hear from you!
