most long arm-ers are not going to stitch your appliques for you- or if they do they will charge you dearly for it-
your appliques need to be stitched before sending to a long arm quilter-
for her patterns it is best to use a stablizer behind the blocks when stitching the appliques down- a good-new sharp needle is a must-
i took a class with one of her quilts a few years ago and we used a fusable non woven stablizer behind each block to stitch the appliques down - worked quite well.
