Windows Automation Project

Creating a script to automate a process of repeated selection of an item within a list provided by a program; clicking opens a new interface, updating displaying properties (of the interface that displays a report) and then exporting csv via a context menu and via printing the report to a file. This script should be transferable to other machines as well. The OS is Win7 or Win8. I am also willing to buy a (windows scripting/automation) tools that get the job done efficiently and which also allow me to make minor changes later-on (E.g. changes the time range data of the report to be printed). A very detailed description of the interfaces and tasks to do via the interfaces will be provided to qualified developers. Please let me know in your 1st contact to me which tool/ approach you most likely intend to use.
