I quilt for other people. I only do hand-guided free motion quilting on my longarm. My prices start at .015 and go up to .06 per square inch. For ruler work, I charge $15.00/hour - very time consuming! Most of my customers ask for block-specific designs (usually 2 different designs to keep it interesting) and a separate design for the border. That costs .025-.035 psi, depending on the complexity of the designs they want. I also charge $5.00 for solid thread and $7.00 for variegated thread, with $2.00 for every thread color change within the quilt.
Hope that gives you some idea of the cost of having your quilts quilted with something other then an edge to edge pattern or panto.
