Indian dress producers, preferred from Mumbai-India

Hi, I am planning to start a business with my sister, who is a fashion designer in Mumbai-India, she is looking for a boutique that can make Indian dresses and she will supply to abroad or sell locally. We would prefer the location to be in Mumbai or along the route from Mumbai to Surat or Pune, Nashik. You need to show some of your designs and she will personally visit to see the quality of the product.
