Facebook App - Sticker Album with trading and sharing

The app has a few features and when you send you bid, please let me know if you will be able to provide all the features - if you can not, please let me know and why. Also, please let me know what feature costs more and why. It's really important to be honest and not bid without this information. I will not consider bids that had not send me a message telling me. You also should provide the app in english but I will change all the texts to other language (I need to see in english so I can translate everything). You will send me all apps texts and I will send the text in my language to replace it. The app wont be in english. How the app looks like It will be an animated sticker album, where the user can paste "stickers" at this album, exchange the stickers with friends or give repeated ones as a form of invitation to other friends. The company produces candy. When someone buy the candy, it receives a little figure with a code. 1) When the user logs into the app, it requires the code to generate a sticker. There will be several stickers and several codes (you dont have to generate the code, just adapt the app to read the code and generate a sticker). 2) After typing the code, the sticker will appear with options: post it at the app Sticker Album (if the user has not another sticker like this); exchange the sticker; donate the sticker to a friend. How the sticker album will look like This album will be a simulation of a Sticker Album (as I said) - you don't have to worry about graphic design (several frames with spaces for each stickers). There will be several pages, like a magazine, where there will be spaces for each sticker. Inside the sticker album, the stickers will appear animated (my agency will design the SWF for it). At any time, the user can acces his sticker album, click in a sticker and will appear the options to trade or to send to friend. There will be a specific page that shows repeated stickers. When the user receive his first sticker, the album will be created. The user's friends will be allowed to view the album of the user and also a page where there will be the repeated stickers. Important: when the friend see the sticker, it will appear static - it's only animated when the user has the sticker at your sticker album. Trading stickers When the user hits Trade, there will be 2 wall posts: 1 one at user's Wall (with a static picture representing the sticker) and 1 at company fan page wall (this way, people can see what stickers others has). Also, when the user hits Trade, the sticker will appear at a app page called Trade. People only can trade one sticker at time. At the app, there will be a page named "Trades" where the user can check the proposals that he had receive about his recent posted stickers. Donating stickers One of the options of the stickers is "donate". When you click, it will appear your friends list - you should select one of your friends and a message with a static picture will appear to him. This will be an invitation to this friend start his album. If you believe something will cost much more (please let me know), please discriminate the costs. Note1: The stickers will also come with a QR code so if you prefer, instead of typing the code the user will be able to use the barcode reader of the phone to read a QR code and go straight to the sticker with the options (inside the app), so it is important that the system will accept the code via parameters too. Note2: You will also have award-winning stickers, but these will not be at the sticker album - after typing the award-winning code, the user will receive message from the app saying that he took a awarded sticker and he will won a prize. At this message, there will be a contact form with send button (user should insert personal data like adress, e-mail, name and phone). The user will send his data to me - I will receive a message via e-mail saying that the user won with all the data.
