I'm sorry that you're not content with your quilting. That can be so disappointing when you've already put so much time and effort into a quilt. If you have the time, or will make the time in the future, then little by little remove that stitching. Even if you only do 10 minutes a day. It will make you feel better inside and out if your quilt ends up the way you truly want it to, rather than a disappointment. It will also end up being a lesson you've learned from. I hope to see a picture or two of your progress and your finished quilt, no matter who ends up quilting it!
Good luck!
