I'd find a shop and take the quilts in for them to look at first. There may be issues with the top, like wonkiness, not square, seams coming apart, whatever. The shop can also connect you to a finisher for quilting. The finisher (or the LQS) can help with the batting, backing and binding. My local LA quilter has giant rolls of batting, so she does not need pre packed batting. She also prefers 4" extra backing on all four side for mounting on the LA. So, suggest to your friend that she find an LQS and see how they can help her.
I'd absolutely LOVE to have handwork done by my Gmother...Good Luck!
