android range finder app

Hello, I have created two iphone applications on itunes called GAME RANGER and GOLF RANGER. These apps are basically identical source code except for different image files. I want someone to use this source code to create android versions of the same app. The app uses the known height of hunting and golfing targets and tells the user how far away the image is. Iphones have the same image capture area but the challenge is that the android devices all have different focal lengths and metering areas. I used freelancer.com to hire someone for this project but they were unable to complete the project. I have the android source code that is almost finished. The app looks and works (a few button sizes are wrong) just like the original except that the math equation is wrong and it is giving the wrong distances. I would like to hire someone who can finish this project quickly and accurately. I NEED SOMEONE WHO KNOWS WHAT IS INVOLVED AND HOW TO FIX THIS!!! If you want the project you have to convince me that you know how to fix this issue. You have a background in math and a strong knowledge of android cameras. You will need to be able to read the iphone ios code as well. most of the work is done, the code is written for ios and the user interface is all done for android golf ranger. You will have to: 1. Help me upload my new version of game ranger (ios) to itunes. There is a code signing error etc.. I cannot figure out and the app is stuck on "waiting for upload" 2. Figure out the math of getting the ios equation to work on the different sizes of android screens. 3. use the golf ranger android source code to port game ranger over to android as well. (different images files). Warning: the ios code does not contain descriptions. Please address this discription of the project in your responses, I do not want generic bids thank you. I have other work that needs to be done if this project goes well, on budget and on time. :) Thanks and good luck....
