Hi there,
I think that the first think is to see your script in order to see where the issue is and value in a better way the work to do and the price to ask for. Please, before to accept any offer, send me a copy of your script and so we will adjust price and time needed to fix the issue.
I'm actually IT Infrastructure Senior Systems Engineer with large experience on this kind of job with Powershell automations on largest companies (100.000 employees + )
Awaiting for your answer,
Regards,
Jose Luis Tome
