I want you to get the adblock clone script [login to view URL] and build an adblock extension for chrome, only difference is that the donate button should link to amazon email gift cards with crazycall@[login to view URL] as the email for the donation amazon gift cards to be sent to.
I have experience in Chrome extension development with various APIs and also for different applications. I think in that sense this projects can be done in less than 7 days and with estimation.
