Web automation written in C# using HTTPWebRequest or anything faster to complete a cycle within 7 seconds (not for Test purpose)

I would like to hire a programmer who could help me to develop web automation written in C# using only library available in .NET Framework. Developed using WPF under Visual Studio Community 2019 IDE using HTTPWebRequest or anything faster. The task is not complicated at all. Only do the following tasks 1. Login to a web page - Retries a specific number of times upon failure - Report error if unsuccessful 2. Performs one operation on a specific page on that site - Retries a specific number of times upon failure - Report error if unsuccessful 3. Logout from the web page These web automation tasks have to be done real fast. The faster the better. (has to be less than 7 seconds) So, if anybody has any better idea than using HTTPWebRequest will also be very welcome but the work has to be done in WPF C# project under Visual Studio Community 2019 only. There should be a simple WPF interface to work with the code asynchronously during the process. There should be a cancel button to stop operation as well. Also, there should be a simple process log keeping with time stamp and time taken on that step in text area or list box for each step through. This project is not for Test purpose. It is for web automation. I need to incorporate the code with my existing project. Hope to hear from you soon.
