AI Expert to enable natural language queries on SaaS app

I have an online SaaS app that is used by kitchen manufacturing companies. It has a PHP frontend and SQL backend, hosted in Azure. We currently integrate with MYOB, Xero, and Salesforce. I need to provide a tool that my Customers can use to ask questions like: * do I have any overdue tasks * Are any Customers behind in their payments * Are I low on stock When they first logon, I want them provided with a list of important notices, similar to the prompts above. This will be on-going work and I am looking for someone who will be available long term. You must have good English and be available for at least 4 hours during my work day, NZT. I want to start in the next couple of days.
