Sorry, no direct answer to your query.
The best I can suggest is to contact quilt shops that are within your target area.
If they don't offer rental time ... ask if they have any suggestions.
If you can't find anything in your area, this LQS offers longarm rentals.
Yes a bit of a distance, but it's a convenient road-trip drive, up the 401 at Belleville.
For sure, it would be worth your time investment to gain some experience,
while getting your questions answered.
Besides, you could turn it into a mini-holiday, as it is in such a pretty setting against Lake Ontario.
