iPhone App - Rain Alert with Push and GPS functions

I want to make an app to serve as a portfolio for a company that intend to open in Brazil to develop mobile applications. So look for someone to develop a relationship of trust, a person to make a long term partnership. If the work was good, I will certainly do other projects. The project is to develop an app for iPhone. The goal of the app is simple, it should notify the user when it will rain. The application will have 3 screens: 1º - An opening screen with an animation / effect but without features 2º - A settings screen 3º - Another screen with information about the app (version, company name, etc.). The settings screen should have a button for the user to set the time who want to receive the alert (when). Another button to set whether you receive the alert all day, or only when the weather forecast is for rain. And another button that the user may opt to receive alerts from a fixed location it defines or receive the alert according to the location of the cell phone (see the GPS location and sends the alert from the nearest location with avalible forecast). The application will be in Portuguese, I will send all text (few do because I want a simple and intuitive app). I do not have art work, so I want someone to do the work of art and programming. I need the developer to help me with the register to make the application available in Apple's App Store. It is essential that the application be approved in the App Store, I want someone who is committed to this. Where the application will get the information to generate alerts? Free from any source. The developer shall be responsible to try to find. I have two possible XML repositories that I have as options, but I'm not sure it will work. So I want someone to look for a possible source of free information. I believe that airports provide this information for free. I want the application to work throughout Brazil. If you have the weather forecast for the whole world is better, but not required. What I need is that the alert works well for Brazil. I have two ideas for the mechanism that will generate the alert: 1 - The application is activated at the scheduled time and then checks the GPS location to find the nearst forecast avalible. After that the application checks the weather forecast for location, if the weather forecast has the word "rain", the alert is sent to the user. This is the source of weather forecast (XML repository) has an output as text. 2 - The application is activated at the scheduled time and then checks the GPS location to find the nearst forecast avalible. After that the application checks the weather forecast for location, it sends an alert if the probability of rain is greater than 69%. This option should work if the repository result as output a numerical result based on likelihood of rain. I prefer this option. The query would be: The probability of rain in the next 12 hours is greater than 69%? If the repository you answer yes, the user receives the alert. I intend to make a free version and another paid. The free version will have a banner on the settings screen, in addition, every time the user opens the application settings screen, you should open a pop up asking if the user does not want to buy the full version (including a link for the paid version ). The paid version will not have that pop up and not the banner. Also when it sends the warning of rain, the app also warns the temperature forecast. This application has some similarities with RainAlertPro, however, is focused on Brazil and he would be a simpler application with fewer configuration options. I dont want to copy it. I need a tool to be able to replace the advertising banner. At a first moment I intend to put the google Adwords, but I need the tool to exchange the banner and to control the number of hits and number of views. Thank you for your attention, I hope to find someone to actually build a partnership.
