Appy Holidays UK

I want a phone app to be built that will allow the user to search for UK caravans, camp sites, bed and breakfasts and chalets to hire for holidays all over the UK. Then be able to choose the place and call direct from the app. Clicking onto the app to enter the first page Page 1: I want a few drop down boxes, the first with an alphebetical list of counties through first England then Scotland, seperated in that order. Once a county has been choosen then the next drop down box below will have a list of towns and cities within that county, the 3rd drop down box will have the four options of the type of accomodation that the user requires. Then click an OK button that will take the user onto another page. Page 2: This will be different depending on what county/town/type is choosen. This page will consist of a list of all the accomodation available within the area. This page will have 1 picture of the accomodation on the left with a brief description of it. Page 3: Once clicked on an individual page for each accomodation will appear with a more indepth description, more pictures and prices plus a phone number. Primarily I would like pages 2 and 3 to be set up so that I can edit them as and when I drum up more accomodation to add to the app. There is an app already on the market which has the exact layout I want but I dont think it is up to [login to view URL] is called Love to escape. If you can get it close to this I would be happy but like I said I want to be able to add the accomodation on myself Reply with HARDY APP as the title.
