Willow Bushes (Sevierville or Knoxville)

Hi! Do you have a willow shrub or bush on your property? Or do you know of any good sized bushes beside roads? We'd love to get some cuttings of willow to plant beside our creek, to help with some bad erosion problems.
Any kind of willow will work.
Any size of willow will work if its branches are in hand/pruner reaching distance.
We live in Sevierville, but drive through Knoxville every week.
Feel free to email me if you have some, and I'll get back with you soon! Thanks so much! (Pictures for reference, and attention)
