If you are near Central IL, or even passing though, they can make
arraignments to do it in a day while you shop the local Amish shops. Try
Otto's Canvas Shop just outside of Arthur, IL. Last time I was there
they had a phone service, typical of Amish businesses.

They made a great towing cover for my Ranger 481VS. Their covers use
fiberglass bows. So they mount small fixtures to the inner gunnel's.
They have never been in the way. Towing with Otto's cover is better
than without a cover and far better than the deluxe Ranger cover. These
are custom, measured, fitted, and sewn for your boat.

Several colors and materials, in different weights are available.
