Android sales personal catalogue application

We are creating a retail application for iphone and the ipad. We are looking for a development partner who can design the software architecture as well as develop the application. The application is required to display all the products in a retail space by Price, Category and brand. Herewith what I will require from the App: - our reps will be using tablets to detail doctors and pharmacists - what we currently use are printed A4's. One product typically have lets say 10 pages, but it doesn't necessarily mean that they talk about the info on each page at each call. It may also happens that you are busy on page 3 and the dr asks you about info that you have on another page. The rep can then easily page to that page in the printed detail aid, but with th tablets the concern is that the app will work like a powerpoint presentation where you have to go through all pages to get to relevant one. Long exolenation, but I think you understand? - basic requirement will be: - reps are split into 4 categories, products might overlap, but order and combination differs. For ease of use rep must only see his or her's specific category. - each category of reps will have about 12 products, each product to have about 12 "pages". - must be able to "flick" easily between different products and pages of each product. - some pages will contain graphs which must have the ability to be animated for a more interactive detail. Ok, that's the front end. Re the back end, will have to have the ability for my inhouse designer to load updated and or new products. As well as add animations if necessary. As mentioned, some products might overlap between the different categories, so to simplify uploading, it will be ideal if the back end allows for uploading a product once and then to simply "tick" a box to specify which categories willbneed access to that product. Dors that make sense? Then the hosting of the, it must be secure, i.e. no-one without username and password must be able to access the info. Also, the app should not require internet access when using on a daily basis, exept to update pages as coverage is not always good.
