Build an ios app for my wp site (a complete offline version) -- 2

I have a WP website that I have built that I need to be converted into an iPad app. The website is part of a display (similar to a trade show display) allows someone walking by to see products, view services and then submit a contact form. The internet connection at these locations is not good enough for the content (e.g. video) and needs to be running natively. Here are two locations that you can use for reference: Location 1: [login to view URL] Location 2: [login to view URL] You'll notice that the Welcome screen is the same, as is the welcome video that plays and the services listing. The other 2 pages are different for each location (image gallery and contact form). The only thing requiring connectivity is the contact form submissions that need be sent via email upon submission (or upon connecting to the internet). We currently have the two versions, running on separate iPads, but will have more in the future. The website was built for HTML, so the design will need to be adapted for native apps.
