Good for you!! As for price to have them quilted depends on the area you live. In my area you measure the length and the width mulitply those 2 numbers, that will give you how many squares inches the quilt has. Then in my area most of them charge 1 cent a square inch for a very simple design....and on up to 1 1/2 and 2 cents. Also if you want heavier more dense quilting they charge more.
But like another person mentiond for another type of quilt you could do a fun and done. That way when your done your done...lol it's quilted as you are making it.
Don't forget we like picturs :D
