How to I redirect to another page after a set time?

You would first create your page with OptimizePress.  

Then add this code in the Page Settings > Other Scripts > Header section:

<META http-equiv="refresh" content="5;URL=http://www.YourRedirectURL">

You would modify the URL to be your redirect URL and the number 5 to be the number of seconds before the page refreshes and redirects to that URL
