Sales Funnel Builder

I have a number of clients who require sales funnel builds. We are developing the content, including video content and facebook ad campaigns. I have been using clickfunnels but considering a move to Kartra and will need my basic sales funnel rebuilding in that, (content is already written) as well as a couple of clients. I have mapped out the various funnel steps using some software and I am working directly with the businesses to develop the strategy and content.
