Web- Based Child Care Administration and Website

I am looking for something pre-built or very close to it since the application is very common. I need a Website for my child care that also has functionality for Administration through Logiin. The application should be MySQL for all records and PHP with user-configurable web screens (colors etc). Application should include Accounting/Bulling etc. The Child Care application should also include an IOS and Android App so Administrators and Customers can check account data such as child's attendance, account status and also be able to pay their child's tuition. Administration should be able to send messages to all customers and customers send messages to Admin as well. Customers can register child through website etc.. More details will be provided.
