Steelwork Costing Spreadsheet Upgrade

I need an experienced Excel freelancer to upgrade my existing spreadsheet for costing steelwork and cladding. This will help streamline my workflow and integrate with a Word document via mail merge. Atn the moment I input a lot of information manually but someone with advanced knowledge could create a formula to do the same thing automatically. Most of the criteria is either a maths formula with a what if behind it. There is another spreadsheet that possibly could be added in or connected to it.

Requirements

- Calculate costs: materials, labour, and plant hire. - Enter quantities using formulas after inputting criteria. - Enable mail merge with a linked Word document. Ideal Skills: - Advanced Excel skills - Experience with mail merge - Strong attention to detail Please provide a sample of similar work done. I look forward to your proposals!
