Design an App Previewer with website scraping abilities

We are a smartphone App development company and we need to design an instant App previewer or demo so our customers can type in some details and an example of an app will be produced instantly and you will be able to navigate through different screens by clicking on tabs. For example from home screen to about us. It will resemble a real app. The first step in the process will be website scraping. A field that will ask for your website. The previewer will then scrap logo's and images that will be put onto the app. The logo will be on the home page and the images will scroll across the page. The second step will be to name the app , to chose the industry (industry specific tabs will be generated based on the information we provide you), confirm the logo (that has already been scraped) otherwise load another, pick a colour scheme. The third step will be to enter email to send a link to the preview for further reference. The forth step will be to present the app, it will have all functions working for example, about us, contact us, facebook links, book a service, find us etc. This app demo will need to be on its own landing page with links to our existing website. Please email me for further information. I would like it all to fit in with our website branding. I can send you links to our website and working examples of app previewers already live online. This matter is urgent for us. Time will be an important factor so please provide acurate turnarounds. Examples of similar work will be highly regarded.
