A wetsuit will work for kayak paddling, and many people here wear wet suits in very low temperatures in the winter. You can get a wetsuit that will be adequate protection until the water freezes for about $160 bucks.
You can search here for lots of threads on wetsuits that work for cold water paddling. Full surfing wetsuits with flexible arms actually work best. Good brands to look for on sale are Oneil, Xcell,
Drysuits are very nice, but not the only solution for paddling. Not realistic for those without large bank accounts. Posters on this board with lots of experience in cold water wetsuts are "Sing" and "Wikle" . Keith Wikle is a very experienced great lake paddler and good person to know about training in the great lakes region.
