Hey, I can do this in a few days if I understand your question good, but let me recap:
-You want to open a popup if any part of your website is opened
-You only want this once per person per day
-There needs to be a delay between the opening of your site and the opening of the popup.
If this is what you want, I can do this in a few days. I am an experienced javascript/jquery coder.
Please let me know if you're interested in hiring me, I'm willing to answer any question.
With kind regards,
Jonas Muilwijk
