Need help: Salesforce data to Power BI (Need as real time data as possible)

I am creating a 'Management Dashboard' in Power BI. This dashboard consists of KPIs mostly from Salesforce. 
The process by my team that is currently being followed is this:

1. Using Salesforce APIs push the data in AWS RDS (MySQL DB). (This data push will be done hourly)
2. Create necessary views by joining tables.
3. 'Get this data' from MySQL DB in Power BI & use these views to create visuals in Power BI.

However in Power BI Pro Service account we have a limit of '8 refreshes' in a day.

Now the client wants this data refresh to be as real time as possible (which is not the case with current scenario)

I need better inputs on this to provide my client with as real time data as possible (somewhat streaming data from Salesforce to Power BI)

Any help would be much appreciated.
