Mobile development

I need an Android app. I would like it designed and built. The Gps app which help parents to protect their children from strangers that may adversely affect the morale of children through specific calls or sms(which children often do not have the courage to talk openly with their parents about the situation created). And even if someone tries to steal the phone - Inform Me helps you collect data from your child's phone. GPS apps - is a very accurate location services for family members. It is a safe way to track your children on the map around the clock. All you need - it's a phone with Android on the installed application. Who needs a tracking service like Inform Me?  Parents with children from 6 to 18 years, whose children attend every day on city streets to school, to relatives, walk with friends or family.  The list of application functions  ✓ Location and maps:  ✓ SMS tracking  ✓ Call tracking ✓ Notice of places: receive notifications when family members come to school or home (this is automatic Chekin!). Important: All family members should know that this application is installed and running on their device, and must be willing to monitor their whereabouts  With Gps apps you can access family information from your smartphone on Android, when you're away from your children and family members Warning: any services based on GPS-technology works when the GPS, Wi-Fi or Mobile internet service is on.  important note: after the successful downloads of the GPS apps while installing, it will take all the information like first name, second name, age, email address, phone number, every information what is require for affiliate page that signup is required and after filling it up it the email address needs to be confirmed and then only the GPS apps is gonna work. I need a back end for the apps what options I can put in and take off the options when a person fills up the personal information. for example my main target is USA, Russia then I need the country the apps needs to be shown on USA,Russia. please tell me how much time is required to create this GPS apps. I cannot spend for the first application that will be created from you. once the apps satisfies me you get lots of orders that is gonna make you me rich.
