Screen recording

Hello

I need someone to do a screen recording of my app which is an end to end walk through. This is for use in a presentation. The screen recording would need to be done on laptop and phone and stitched together. I need someone who can not only do a screen recording but also clean it up and color correct so that the video looks really professional and not the typical shaky videos. I may need voiceover depending on your accent. Please NOTE the app is very simple so this is not a complex video.
