Hi,
I have gone through your requirement in detail. I understand you need a script that should be called when your server/machine starts. Similarly, a script needs to be called on shutdown. Status should be logged.
Please note, it will require privileged access. However, I won't ask you to share root credentials with me. You can share your screen just for the purpose of script deployment and testing via TeamViewer/Anydesk/anything that works for you. Don't need any access for script development.
Coming down to delivery, the same can be delivered to you in one business day along with basic KT on usages and statistics. I understand you have a very limited budget for this project but my bid is the minimum I could have for you.
Rest assured you will get a proper solution and 15 days of warranty support after the script is deployed in production. Coming down to my capabilities, I am a Solution Architect working with several clients with the provided resource to address business challenges. My area of expertise is Linux, Unix, Shell scripting, Python scripting, Automation, DevOps among others.
I hope to bag the project and get you an awesome solution in the minimum of time and resource.
