run a demo example for AWS IoT core using Java script

We would like someone to consider this repo
https://github.com/aws/aws-iot-device-sdk-js-v2/tree/main/samples#browserpub_sub
And show us, with all the steps, how to publish and subscribe (from code running on browser, not server). The outputs are the following:
- A video showing the whole scenario
- A meeting with us to show us how it works exactly and guide us to do it ourselves
Please submit your real budget for this. If you are familiar with nodeJs and Java script, this should take less than 3 hours of work
