I have had a midarm for 5 years and recently have been quilting for others. I am in Central Califonia, close to Fresno.
My fee for a loose panto edge to edge is .01 per sq in. for a dense panto it is .015.
I do have a minimum of $35. and this is because a small baby quilt 36x45 would ony be $16.20 which would not make it worth my while to quilt it.
I charge $7.50 a yd. for Hobbs 80/20 and $7.25 a yd. for Quilter's Dream poly select.
I think my price is fair for me...I am retired and this is my hobby but I would think that it is a little low if i wanted to make a living with it.
