Hello,
Looks like something has changed on Amazon website and that messed up your scraper, it should be a straightforward task, and depending on the current code should take even less than the estimated time.
I've been working extensively with scraping (using python) on my day job for a month and am confident we can tackle this issue with no trouble. Although I am new to free bidding freelancing, I've been working with software development for almost 8 years.
Any doubts you have, clarifications you need or if you would like me to tackle this project, feel free to contact me.
Thanks for the attention
