Help Making Or Finding A Wordpress Optin Script or Box

I'm wondering is someone can tell me how t get a wordpress optin that comes from the bottom of the screen to work? When the site is visited it comes up about 1 inch from the bottom of the screen to input a name and email, auto responder info in there about 5 seconds once the site is visited.

This is something that I've been searching for, any and all help is appreciated. There are some other features I'm looking for as well. Thanks again. PM welcome also.

I don't know of any 'pop up' ones but this is a nice one for your sidebar:
