Hi,
I'm a full time IT Contractor looking to bolster income with some ad hoc project work like this. It's my first proposal, so apologies if I've missed any established etiquette of the site.
Obviously I haven't seen the script your using, or have insight to your environment, but I'm pretty savvy with Powershell and I'm sure if I took a look if I could throw together something meeting your requirements. I've crafted numerous automation scripts throughout the years. Mostly around mailbox health checks and AD User account manipulation, but it sounds like you're looking for just some general refactoring and expansion.
Would you be able to zip up the scripts / files you're using and send them to me with a list of specific requirements? Screenshots of the errors you've alluded to, and let me get back to you in a couple of days? I'm not interested in billing for my time unless I can deliver what you need
