Material with labor together

Custom properties. I'm debating going this route to match our current spreadsheet and I'm needing to create several other custom properties anyway to price the way we price work, so it makes sense. From what I'm looking at it requires quite a few custom properties to do what we currently do in excel but it's doable. I'd have one item such as brick with a material cost and a production rate variable. I'd have custom properties for crew, crew payroll, labor burden, and production rate. I'd also have brick material cost and tax. These would likely be inherited from a folder that would have the crew makeup for that would be performing that phase of the work. A formula combines all these into the labor cost per brick and material cost per brick. Then overhead and markup are added and we come to a turnkey price per brick on one item that includes labor/material/sub etc.
