Hello,
Thank you for posting your project here. I believe I can regularly scrape data from websites that you provide and upload the data to amazon accounts as well. I'll automate the scraping process and also the uploading process to amazon (as much as can be done)
The percentage increase in price shall also be auto implemented. Unavailability of UPC is not a problem for me - if that is not a problem for you. Do I need to generate UPCs at any stage?
Since you asked, If there is a constant flow of products (that is, there are at least 2000 products in a week), I'll ask for $45 per every 1000 records (products) scraped, processed and uploaded. That is, USD $ 0.045 per product successfully uploaded. No other fee is required for writing new scrapers every week or scraping data.
A lot of websites nowadays use dynamic javascript elements that make it hard for traditional scrapers (HTML based) to access the data. I use Selenium with Python or Excel which enables me to mimic user activities via browsers, which make the websites 'think' that I am a normal user just navigating through the site. This enables me to access all elements and data and finally scrape anything that a user sees on a site. I have successfully completed several webscraping jobs in the near past - and you can see that on my profile.
Please let me know if you have any questions, I'll be glad to discuss.
Thank you for your time.
With best regards
