I have an online service where I want to show my user base steps to carry out various functionality in the service. I want to achieve this with a video. The video can either depict the actual steps using screen recording or I can provide images that can be arranged sequentially to show the steps. I may also need narration and a script to effectively communicate the steps. I'm not looking for anything too advanced but something that communicates the point effectively. I am open to suggestion on approach too. Cost is a factor. I'm also looking with someone who has experience doing this.
