Webscraping with Python, Syntax for a research project.

We are looking for someone who will write a python code that will allow us to count the number of ads on a job employment website and will capture the ad content (job requirement, working hours, etc) - dynamic content (javascript). The data should be available in an excel file, the code should allow this for a longer period of time. We are conducting scientific research, so if you have a background in this, it is an advantage :)
