Video framing and sub-titles

I'm making a series of ONE MINUTE videos and need someone to add the frame, titles and narrative sub-titles. They will be just a simple talking head, mobile filmed, and deliberately casual. See mock up below.

They need to be Instagram and Linked In friendly.

There are currently 18 planned. BUT PLEASE PRICE ON THE BASIS OF BATCHES OF THREE. Will be ready to go in a couple of weeks but we can sort out the frame and video titles beforehand, then follow with sub-titles as I complete the content.

Many thanks!
