Adding features on existing Mustache app IOS code-

Calling on IOS programmers. Please provide a quote for the following project.  We have recently purchased the codes for Mustache Bash App for reskinning. [login to view URL] We are making the design changes ourselves, but we need a programmer who can work on the code and add 3 features to this app: 1. Integrate the Aviary SDK.  Purpose: This is gives users additional options to edit their photo.  Integration: In the screen where users are editing the image, you will add another icon at the bottom of the screen that will open the Aviary interface. Aviary will need to be customised to fit the rest of the app. Customization will be limited to the standard changes allowed by Aviary. More details will be given to the winning bidder.  2. One-Click addition of stickers. Purpose: Make it easy for users to decorate their picture with only one click. Integration: In the screen where users are editing the image, you will add another icon that will apply this feature. When this icon is pressed, the app randomly selects from a set of stickers. These are placed in predetermined parts of the image. The user can then edit the image afterwards with the other tools. More details will be given to the winning bidder. 3. Add an Option to remove pop up ads.  Purpose: Give users an option to remove pop up ads. Integration: In the start screen, add an icon that will start this feature. Users are asked if they would like to pay 0.99 to remove the pop-up ads. Agreeing to this in-app purchase, users will no longer see pop-up ads when they use the app. Programmers, please let us know how much each feature will cost, and how long it will take to develop. Show us examples of apps you made before, and let us know if you have implemented these 3 features before. Thanks.
