Cellphone/TV graphics in film

Hello!

I need someone who can put graphics on both TV and cellphone screens in a film.

This includes:

- shots where the lead character is texting/looking at texts and we see it on the cellphone screen. I need someone to create the cellphone screen/texts (the footage just has a blank cellphone)
- shots with a TV in the background where we see something playing on a TV screen (in the footage the TV is off and just a black screen)
- replacing shots of a computer screen with other graphics

There are approximately 20-25 shots like this varying between 3-8 seconds each.

I can give direction on what should be on all the screens.

Please include samples of comparable work if you have them.

Thanks!
