WTB: Code Examples

Hello!
I am stuck at my new project and I can not move forward.
I am looking for code samples for following things:
- User registration/login
- Google maps navigation posibilites
- Adding things into database provided on the server (MySql preferred) - Normal user can only read database, admin can add things into databse via app.

I am willing to pay if your code is working.

iOS (URGENT)
Android (NOT URGENT)

Regards,
G.

My budget: 10-20EUR per working source-code via paypal.
appx: 30-50 EUR for the register/login with working PHP source code.

If you are looking for registration/login sample, I already posted in Code Snippet section
