You tube videos- Add logo, royalty free music and pic.

Hi
I have 9 videos on you tube (unlisted- all between 2-8 mins long) that I want to put my logo on and rather than having a freeze frame of me (thumbnail?) at the start of the videos I want to include a royalty free picture that I have and have the words added 'Hypnobirthing online package' added with the title of the video. Then when the video ends have the royalty free picture back up. I have added the video links, my logo, the pic I want to use. Words need to be added to the pic for each video at the start. Can be the same at the end. I'd like to have it done in you tube so I don't have to upload all the videos again. Thanks
