I would potentially look into Zoom as well as an option for delivering remote training.
In terms of pitching to corporates, I think the big question to answer is how will it help their staff, and what is the benefit to the company from this?

The buyer might be someone in the HR, Corporate Wellness, or training/education space, and I think the best way to understand that will be to look at your current customer base and the value you provide there and see what is transferable/able to be leveraged for a corporate audience.

I am happy to connect more in the future, feel free to reach out whenever suits.
