Hello,
Thank you for the smartly detailed description, I will be happy to build this Selenium solution for you, following your specifications precisely. I have done A*. There are some technical requirements the server will need to meet to build Firefox, but we will get to that. I will use Python.
I will likely complete the task in 3 days, getting all the details just right may take a day more or two. I will be in contact with you regularly, and will count on your timely input whenever needed.
You will enjoy free support and free fixes (if needed) even after project completion. I guarantee you will be very pleased with my work. I aim to earn an excellent rating on every project, and am willing to do whatever it takes to reach this goal.
Would you mind, please, responding to my proposal so that we can discuss the details and get started? Thank you.
Looking forward to working with you,
George
