Hi Tamara -- I'm an amateur eventer here in Knoxville and ride/train with a few people here in town. I can give you several good recommendations. Send me a private message on here or you're welcome to email me (my name is Holly) at firstname.lastname@example.org.
I've foxhunted in Knoxville and they are WONDERFUL, KIND, and very INVITING. However, if you are considering fox hunting here versus "very low level eventing," then I'd absolutely have to go with "very low level eventing." A number of those hunt fences are not for the faint of heart (3'6"-4' on average). I event beginner novice and novice and I always hilltop (with the option to jump, when/if I see fit) when I ride with the hunt here.
