Hi,
I have some experience with scraping bet365 odds.
It is hard to scrape flash websites, but we don't need to use there flash website.
I have one trick for that to be bypassed.
How many times you want to run script daily?
If you need to run many times, bet365 website will block your IP, and you need to buy some proxies.
That will be about 20 or 30 $ per month, I don't remember, you can see that on hidemyass dot com
You need to buy professional proxies, so we can change them each time we are blocked, or to change them every 15 minutes, to not be blocked.
And I think excel file will not work for you, it will be better to store in mysql database, and then using Web app, which will run locally, to show all that odds.
I use ruby and ruby on rails for that.
Message me if you have any questions and I can start working immediately.
Thanks.
