Hi there,
Thanks for this opportunity! I have 14+ years of experience in Web development and after reading your requirements I'm 101% confident I can help you with your task. In fact, just to test my programming knowledge, you can throw any kind of problem at me right now (not necessarily related to your project) and I'll solve it for you.
I understand you're looking for plugin + Chrome plugin with those features but there's is none like that at the moment. I can create it for you. It will be a custom Chrome extension to insert a button on Amazon pages and on click it will send using a WP API to a customWP plugin that will save that ASIN code in the database and show it to your in the backend.
When you choose to work with me, you get a partner that actually responds to messages/emails/calls, gets things done and is committed to helping you succeed.
Moreover, my english is great so you can be sure that there will be no language barriers.
When you're available let's discuss further and if we decide we're both on the same page, we will then get this done ASAP. My price and TAT is final as that's the actual time it will take me to develop what you want (I always try to deliver faster but just in case, I opted for 3 days).
Looking forward to helping your reach your goals and build a great business relationship.
Regards,
-CR
