I think that you need to change your attitude or your negative attitude will be reflected in your workmanship on the quilt and at work toward this lady. Perhaps you should not have said yes but you did and now either change your attitude or tell the lady you do not want to make the quilt. Just think of the joy that the lady's DD will have when she gets the quilt with all her high school memories. I have not yet made one of these quilts but a friends DH has made several so it can't be that hard. Since you have made one already then the second one may be easier. Do the best job you can with a happy mind and it will be great! As for $$$ take what ever she will give you or ask cheap or free and make this a gift for her daughter also. Remember nothing is perfect!!!!!!! Also remember that "NO" is not a 4 letter word!!
