I say go for it. I am certainly not even remotely close to a professional level quilter, but I am careful with my piecing, creative with my layouts and quilting, and always include the person paying for the quilt in my ideas for the finished product. I've made several quilts - 4 memory and 4 or 5 t-shirt quilts for people who have paid me for them. I let them know ahead of time what the approximate cost (WITHIN 10 - 15% ) will be, and then I totally agonize while putting the quilts together, worrying about whether the person paying for the quilt will be happy with the finished product. Happy to say that every single person I've made a quilt for, so far, has been totally thrilled with them. So again, I say go for it. But do not give your time away. Make it worth your effort - for you!!
