Construction office side

Im a 17 year who helps his dad on the office side of construction. Division 7 which would be the insulation, strapping, siding etc.

I do all of the measuring, estimating, bidding, email etc. I currently use Bluebeam revu for measuring jobs for Square feet and linear feet. Excel for doing my breakdown for the labor pricing.

I need help on what softwares to use.

Also I am not a big tech guy so help on pc to use, monitors, laptop etc would be helpful.

My father has been a sub-subcontractor and now we are moving on to subcontractors so we’ll be getting jobs now from GC. I’m the only person on the office/tech side in my fathers company of 10 guys total.
