Hi
I have experience to make the web crawler script using the python crawler package.
At that time, the most issue was to fix the google captcha.
Other cpatcha features such as the adding the text through the image is possible to pass, google captcha require the key.
Anyway, I fixed it and it's working well .
The code will be working like that, crawling the data, exporting to the CSV,
I think my previous job is similar with your project. so if you are interested in me, let's discuss it more details via chat.
Thank you.
