Can anyone help me with some advice as to how I can create a short video to help promote my products?
Video is a great promotion tool. As previously suggested start with what your goals are for the video? What outcomes do you want? How long should it be for your unique audience?
I personally would not use Fiverr for this. It always costs more than you think for video, whiteboard and explainer content - so beware. You can create video very easily using your iphone or a live streaming platfform like Blab (which will record and send you the link), adding a professional top & tail using Google Editor then uploading to You Tube or Vimeo to host (depending on your goals). Or you can also try live streaming video platforms (again, depends on your goals). Be aware of lighting, sound and scripting. Plus I suggest using a Teleprompter app for recording (best $15 you will ever spend)
You can have a look at my video channel for more tips and how to's
Hope that helps, Have fun!
