Subscribe for a new platform

Hello, the project is about a new platform, I need people who can subscribe on it.
These people should be for coaches, cook and other professionals but they have to be from UK , States and Europe.
This platform can help clients to overcome the challenges they could find during the booking process, the payment and all the difficulties in their work. I will share the platform with the people I will work on it.
Could you help me to find these professional people and make them to subscribe?

Thanks

Fabio
