I have had 11 quilts done by professional quilters, one uses a long arm and one is a genius on a normal sewing machine. I have paid between $80 to $220 for a single quilt, depending on size and design. I have never had anything come back that looked as bad as yours. I cannot imagine even paying for the quilting done on either quilts, I could manage either myself, and that's not saying much.
Here's a few examples of excellent quilting:
These are hearts!
