I'm very experienced VBA developer, I'm developing tools and add-ins using VBA script for more than 8 month and
I was developing tools using apps script(very similar but for google apps) more than 1 year ago.
I'm working with tooling team and nearly everyday in my work I develop scripts similar to what you are asking.
I can do the task easly and it will be well tested and efficient, recently I developed a package of scripts that automate most of manual work for project leaders and managers in my work for example application that updates MS project based on values extracted from excel sheets, another script that compares two sheets, create another one with results, add-ins to view form to accept inputs then update the document fields then push it SVN repositor, script to enter a project structure as excel (with taged files names) then the script generates the folders and replace tags with values and copy files to the correct folders then push the project structure to SVN repository using batch script file .
I guarantee you a high quality service
