Hi,
Your project sounds very interesting and simple enough! I believe that I'll be able to perform the task perfectly, but I could use some additional information :)
I have over 15 years of experience as Physics and Math teacher; but, I've also done some VA work, which included scraping using Mozenda and Excel and scraping with a my custom made software.
You're welcome to check my reviews and should you have any questions, I'll be happy to answer.
Kindest regards.
Milan
