I'm not in the area, nor have I used them, but a quick web search turned up Forstall Art Center. Per their website, they sell Highwter and Standard Clays, both of which make good products. They also offer firing services, but you have to purchase the clay from them.
Sometimes a way to break a funk is to take a class or workshop on a focused topic in a new area. Last year I took a hand building class on making bird bath. This was quite different from my typical wheel work.
I learned some new techniques and its always great to see how somebody else works. More importantly, it really engaged my brain about new possibilities. I've not made any more birdbaths (yet), but I was able to use it as a stepping stone to make many new items of my own design. I am sure I would not have done this without the inspiration from the class.

With a weekly schedule, you may need to consider the "paint a pot model" where the campers pick out ready made bisque items to be decorated/glazed and then fired. Going from wet clay to finished product in a week is a challenge in an of itself.
Sorry that the decision to handbuild isn't your choice. That sooooks. But, in my reading of your posts, the wheel was a method of "creating the canvas" upon which you expressed your considerable decorating talents. While I still make things on the wheel, I started handbuilding over a year ago because it allows me to make things (size and shape) that I can't do on the wheel. Handbuilding has opened new doors for me to be more creative in clay and my mind is engaged in an all new way. Scale wise, this may open some opportunities for you to make bigger pots. Shape wise, you may be able to create forms which are more suitable for your decorations. I have no doubt that you will find a way to make nice pots without using a wheel. Good luck.
