If you haven't already connected with your local conservation district, I would recommend doing so. Some invasive removals require the use of herbicides which is often beyond the capability of most individuals and could potentially damage the environment if applied incorrectly. Most conservation districts can help you develop a long-term strategy for controlling invasives and may be able to help with their removal.
