Maybe I can help by telling you my quilting ratesand I would be happy to send you a brochure which has the rates.
50x50=2500 sq. Inches is the size of your quilt.
If I baste a QT 2500 I charge 1/2 cent psi = $12.50
Edge to Edge is 1.5 psi = $37.50 ( edge to edge is usually freehand or pantograph)
Custom Quilting is where you request a certain pattern quilting onto your quilt and is usually very detailed with in the ditch, outline, or specialty stitching. For this I charge 3 cents PSI 50x50 =2500 x $75.00.
If you request specialty stitching in borders I charge $20 per border.
I also charge $1 for new needle, $1 for each bobbin, and if I change colors $4 per color.
I hope this will help you.
Thank You :)
