Welcome to the Quilting Board!
My LAQ charges .01 per square inch for basic meandering and her prices go up for custom quiltings. I think she charges a flat rate (depending on the difficulty) plus .01/sq inch but it's been a while since we discussed her rates and I've been very happy with her meandering so haven't wanted anything else so far.

I did some searching online to see what others did in their LA business. I made up a brochure to give to people so they know what they have to do to their quilt before they brought it me. It made it easier to LA quilt for sure. I know Ididn't give you exact answers, but researching online to see what others do and then customize it to what you want. Good Luck and enjoy!
