I see you have completed a similar project for another freelance user, so I imagine that this will be very simple for you.
I prefer original code that we can own, without adding credit to other sites.
I want this on-click popunder to work once per browser session, or once per day. I would also like to set it so that it pop-unders one page, then waits for three more clicks or page views, then pops another page, then waits for three more clicks or page views, then pops a third pop under page.
I need to know that you are 18 years old or older to work on this project. Please quote me a fair price, and estimated time of completion.
