We have 2 requirements:

1. We have put the mobile number in the registration form so there it will be all mobile codes showing by default (but remember i will put the codes by myself of specific countries) and the user has to just enter the mobile number and on the right or down side there should be option of privacy (i.e. Visible on profile or hidden) same like facebook. 

Note: When any user registers and if he try to add the same mobile number which is already registered with other user the registration form should not be proceed. (like facebook) i cannot use 2 mobile numbers at the same time on my profile.

2. Same with the Birthday, we need the complete privacy for the Birthday option like some users wants to show their date and month but they don't wish to show their birth year like this kind of privacy features we require. 

Can you please send me the details what you do what not? with the price quote. We need to done this immediately.
