Hi @jyoti-thelight the gig is technically not about buying and then I will deliver the product to you wherein a timeline can be predicted with a margin of error to about an hour or two. It is a professional service that is somewhat dependent on the internet connection of the client during installation of the Linux operating on a computer that is why I did not put timeline into it.

After instatallation it has to be tested whatever features are installed on the server. Testing can consume unpredictable time.

It is expected that clients will ask numerous question during and after the installation. That question and answer alone can also consume unpredictable time :-)
