android version for existing iphone app needed

i need to get an android version of my existing iphone app. * the iphone app contains a main screen with map view and position marker. in the main view the user can select his position, which is translated to a readable address. the user can also type in an address manually. * everytime the address changes, the app needs to make a json call to my server to get some service infos for the selected position and update an "order" button accordingly. * when the user hits that order button, one of three different order screens need to be shown depending on the previous json response from my server. * in order screen 1 the user needs to be able to make some simple selections that will then be sent with his order. * in order screens 2 and 3 just some date returned with the previous json response need to be displayed. * there needs to be a favorites screen where the user can add and manage his positions. * there needs to be an options screen where the user can make some yes/no selections that need to be saved in the app for future use. the options screen should also have a sub screen where the user can enter his personal data (first name, last name, phone, email) * info screen - just show an html file from my server i please need an android version of my app that does exactly the same thing as the existing iphone version. if possible, it would be great if you could take care of the interface adaption. i basically would like the same look and feel as in my iphone version, but make use of adroid ui elements when needed so that the app "feels natural" for android users (like a real android app, not an adapted iphone app). accurate, clean work (especially on the frontend) is very important to me - the app needs to look really nice with all ui elements positioned and aligned nicely. if you are interested in this project, please post some references and a first price estimate. i will then send details to my project to the workers that best fit my needs. please contact me if you need any further up-front information. thanks a lot. martin.
