Sorry, I cannot help you with where you can take sewing lessons but I can only encourage you to follow your dream. Changing careers can be very scary especially when you are in a stable noble profession. But I feel you should follow your hear because that is where you will excell. Maybe God is calling you to do what he intended you to do. You will never know unless you try. I would look into a career as a buyer and design on the side to start and then sink your teeth into it!!! Being a buyer will give you a good sense of the industry and what sells!!! You will also make good contacts to launch your own line!! Best wishes.
