Make an animation how to put pieces togetherr of a frame

Hello,

I have a drawing of a frame in sketchup. To show the user how to build the frame, I would like to have an animation. So this part first, then this, then this ... so from scratch to complete frame. I add the drawing to give an idea.
Please explain what you will be using to do this and I have to be able to do some modifications myself afterwards. Note: this animation can not be in your portfolio for publicity as this is a dedicated task.
