Facebook application needed

Client need an experienced Facebook application developer to create a new app. The concept of the app is around offers/surveys completion to trigger virtual currencies. The concept of the app is around offers/surveys completion to trigger virtual currencies.

I - User interface :

1) A user control panel visible directly on app homepage:
- allows users to see history of their completed surveys/offers.
- shows the number of VC's triggered by their surveys/offers.
- shows the number of invited friends.
- shows the amount of VC's triggered by invited friends.
- shows a ranking of VC's triggered among friends. (and if possible among all app users)
- shows a ranking of number of friends invited by other friends. (and if possible by all app users)
- Total VC's triggered by a user + VC's triggered by his invited friends users (and so on if possible) = a score that gives him a ranking.

2) A page/tab/page part that states weekly and monthly VC's triggered by all users.
- this should also be able to list triggered VC's for each beneficiary (see what beneficiaries are below)

3) NO "redeem price" tab/option : VC's triggered by the offers have another goal. We'll share this with the chosen worker.

4) A "beneficiary" tab/option :
- lets the user choose the beneficiary of his VC.
- User has to choose the beneficiary of the VC before he completes offers.
- at each new offer completion, he can choose a different beneficiary.
- he can choose among already available beneficiaries.
- He can create a new beneficiary. As of now, my thoughts are to limit the creation of a new beneficiary to a predefined database. However, I see advantages not to do so. We'll discuss this matter with the worker's suggestions.
- ability to 'like' benericiaries
- user is able to browse beneficiaries. Beneficiaries that will have a description attached to them. From the beneficiary page, users will be able to start completing offers/surveys whose VC's will be destinated to the beneficiary in question.

5) Integration of the offers :
- it could basically look like the app from a link for above.(for the offers page only)
- shows the amount of VC's triggered by each action.
