Chatbot Creator on Zoho

I'm looking to use a chatbot to convert website visitors to leads for my business..
My website, ---------- has a chatbot. That is technology, not a person. Please don't apply to respond to website visitors. We need someone to develop the automated responses to visitors' inquiries.
.
We use Zoho which has many different chatbot options. I need an automated chatbot to convert visitors to leads.
These are Zoho's options:
Zia Skills
Dialogflor
Webhooks
Watson Assistant
Azure Bot Service
SalesIQScribt
We need a dialogue flow/tree to determine why are they visiting the site and to qualify the leads. That's where you come in as a developer (not an admin assistant).
If our pay rate is too low, please let me know.
I will need to check your references so please include them.
Please put the subject/title of your email/application as "Chatbots are my Jam 2021" so that I know you read this.
