Hello,
I have developed quite a few chrome extensions and would like to work with you on this project.
Based on the requirements you have mentioned, it seems like you want to scrape a webpage and find a web url. This fetched url needs to be sent back to your backend using some REST API.
I didn't understand your point about "The extension should also be integrated with Social media like : Facebook - Linked in - Twitter and also other tools like Buffer and hotsuite." What exactly is this integration?
Regardless, it would be nice to talk more about what the scope of the project is. My technical knowledge about implementing extensions should suffice in getting this done.
Thanks, hope to hear back from you.
