Need someone to create a complex workflow for my CRM

I am building my Sales CRM in monday.

My goal is now to have an overview of the total Sales Volumes for a specific time and / or a specific client. The Sales are tracked in different boards and the clients are curently “items” that are different in each board.

The entire setup and possible solutions are hard to explain. So I would prefer to solve this in a zoom call. Happy to pay for the consulting.

Thank you,
Greetings
Michael
