buil respnsive lead generating landing page with api key integration to external CRM

For a project developer in Belgium, I need a responsive landing page that generates leads and links that contact form input to an external CRM through an api key like this one: <iframe style='width:400px;height:300px;border:0;' src='[login to view URL]' allowTransparency='true' ></iframe> (it's not the exact code, it's an example) if you go the the website: this should happen: [login to view URL] the words (something about savings accounts or pension funds or perhaps even the user interface one sees when he opens netbanking) should "fall down" for a few seconds and then the following landing page should appear (= the sollution) The landingpage should look a lot like this one: [login to view URL] Lockwood (real estate) I'll provide the texte (in Dutch) and the images and plans. The website you would be building a lead converting landing page for is this one: [login to view URL] It should definetely be responsive. Once finished, I will be asking for tweaks and minor changes to be made in the design. It will also need to have a "thank you" page if someone filled in the form. Perhaps on that thank you page at some point we will have to add a lead pixel (if we run campaigns through affiliates) a lead pixel could look like this one (see attachment) If happy, we can build more landingpages for other websites (5 at least) Regards,
