Hi @raff_rizzetti
No, there is no paid support, only free.
I would estimate a freelance developer would take 3 hours total to create and test the query. This would cost anything from $60 to $150.
That said, I am not available for freelance work. You must find another developer who would be capable of performing the task.
For reference, there is a good doc here to get you started:
