Need price for quilter

[polkadot19]

Quilter put together a  60x80 quilt top from 10 appliqued squares I had. I picked out matching fabric for front and back of quilt and paid for it. Quilter took squares and completed a beautiful top. I took it to another quilter (the first quilter recommended) to do actually quilting of front and back. She charged $100. I returned quilt to first quilter to complete edging and adding a label I purchased from etsy.com. She does not know what to charge me and I certainly don't know. Can anyone help me since I have no idea what to pay. I did ask her at the beginning what she charged but she said she would figure it out. But, this was not the case. I need help with paying her a fair amount for her work. Thanks! She's bringing it by in four hours.
