Adding features and changing layout into existing iOS source code

I have bought the source code from [login to view URL] which is a 2048 game. 1) I want to have the same features as shown in this app [login to view URL] which is also using the same source code, just that it has added main menu page on the storyboard with 256, 1024, 4096 game and facebook leaderboard features as well as winning game sound. 2) I want to have 128, 1024, 2048, 4096, 8192 game. 3) change the layout of the main menu and facebook leaderboard. 4) adding “silent” to allow player to mute it when playing the game. No graphic and sound files for your side as all these will be provided to you, all you need is to implement it into the source code. I would also need you to integrate Ad Network as well which I will give you my Ads ID. After completion, I might need you upload to App Store if I am unable to do it. And if there is any rejection on the submission, will need you to see into it. Before you quote me the price, please download the one uploaded to the App Store and make comparison with the source code I am going to provide to you, so that you can understand clearly. Lastly, will need you to sign the NDA form before the project is awarded to you. Of course, I will need to get this done as soon as possible because I have another few more projects piling up right now. Kindly reply “Let’s Go” to confirm you have read the whole job post and are ready for this challenge and business opportunity. We look forward to working with you :-) Thanks! Peter.
