Hi,
I am an IT Specialist with 10+ years of experience in software development and system administration. Have delivered quite a few scripts at my day job and some as a freelancer also,
I think the best way to accomplish this is through a VBS (VB Script) as it is pretty easy to "read" so it will be easier for you to customize it in the future. This script will be scheduled to run whenever you need to (each night, only some days etc.)
I expect to finish it in a couple of hours, but I state my bid for 3 days for reasons of testing and acceptance.
Looking forward to hear from you,
Kind Regards,
Bogdan
