Taking orders for someone to sew clothes

My friend has a business of selling stitched female clothes. I'm in another city and she made a deal with me and my sister that for every dress that I will struggle to get sold in my city, I'll be getting some profit ranging from 50 to 500 rupees, depending on what type of dress it is. So I call my female friends and relatives, and sometimes when I meet them, I tell them about the dresses, take their sizes and send them to my friend in the other city. She stitches the dresses and gives them to my sister who is also working with us. My sister then delivers the dress to my city. Is this income halal?
