Beautiful quilt and quilting...I am so new to this but what if you took her with you to pick out the fabric and the quality that you want to work with ....let her buy the fabric and she will see how expensive that part is then charge her your hourly rate....bet it will be around that 12 to 1400 rate....I could never afford to pay that but if money is not a problem and she wants it and she can pay it then it should not be a problem for her are you...that way she sees how expensive batiks are and you get compensated for your talent on piecing and quilting..
