Clarity Pre-launcher Plugin

I need a prelauncher plugin based on prelaunchr: [login to view URL] I need the plugin to use a sign up page and a re-direct page. If you look at the code it changes the template of the page after the form submit. I need all the information from the thank-you template on the second page. Then I need to also include an optional sitewide privacy on all other pages so you'd need to be a user to access. So I need to combine these two plugins. Prelaunchr and [login to view URL] On the prelaunchr pages I still need to be able to add content and design elements to be able to style the page, and custom css functionality to be able to style the form and secondary page elements. It needs to be responsive and pass the wordpress assessment as I need to use it and then also let other people use it. It also needs to integrate into email marketing platforms, such as Mailchimp, Aweber, Campaign Monitor etc. Attached is a Mock-Up of what the backend should look like. Let me know if you're interested and what the cost would be.
