Can you clarify a bit more what type of assistance you are looking for? Training a clematis is relatively easy if it is a young plant but you need to be on top of it during the growing season. If the growing tips are too long, it is very easy to damage or break them, so often weekly, perhaps even daily, attention is required to guide the shoots in the intended direction. If the plant is well-established, training can be more difficult, as the plant has already decided how/where it wants to grow. Really, only the newest growth is amenable to training without problems.
