Illustrator needed for work-themed cartoons - job 2 of 2

I'm looking for someone to produce simple cartoon illustrations for a work-based comic series I want to use on social media. I have attached one simple example that gives an idea of the simplicity of the illustration. These will either be in one or four panels and tell a short story or send a short message. I will brief each one in so the ideas will come from us. The characters we develop will need to be easily reproduced across different comic. If apply, please ensure you send some examples of your work in a portfolio that is easy to access. Do not contact me outside of Upwork.
