I will deliver your project using the following:
- Google assistant actions SDK
- Dialogflow
- Flask-assistant as backend.
- python as programming language.
I designed rich chatbot which accesses database using Google actions sdk and Dialogflow and Flask-assistant.
so I think I can :
- design dialogue we agree then
- implement that dialog with dialogflow and Flask-assistant then
- host Flask-assistant app on Google cloud to provide excellent performance then
- test and send for certification.
if you choose me, I think you won't regret.
best regards
