Need Druid expert to give us consultancy

We are working on a web analytics project in adtech domain. For that, we have chosen Druid to be our database for our click logs. Need someone who has already worked on Druid. To give us consultancy on that. We won't need you to do any code. We will just ask your recommendations while finalizing DB schema and other configuration settings. We also might ask a few questions like how to add extra column to datasource in production etc. I am willing to pay as hourly basis for this project. And we will need your help for very long term on it. Please quote your hourly rates for the same. I am hoping I will need 5-10 hours of yours per month for many months to go.
