PHP interface for bitcoin, litecoin and dogecoin

Background: I want to create a public API similar to this: [login to view URL] The API allows user to create a new, unique wallet address and when coins are transferred to the given wallet address, the API will call the user provided URL. But unlike [login to view URL], I want my API to support many coin types, not only bitcoin. The setup is: Server 1 is a web server running LAMP stack. Server 2 is a VPS server running any Linux distro you prefer, for example Debian. You will not be given access to either server, you must have your own test server(s). Your tasks are: 1) Create an installation script that will automatically download, install and setup the Bitcoin, Litecoin and Dogecoin clients to the server. The script must setup the coin software to start automatically with the system. The installation script can be made with any common scripting language. When I test your work, I will have a fresh installation of Linux running on Server 2 and I will run the script. After the script has run, the server 2 must be fully setup with no other configuration needed. The idea of the installation script is to provide an easy, hands-off method of installing the system to any new server (assuming the new server has the same Linux distro). 2) Create the PHP code that will run on Server 1. The PHP code communicates with the coin software running in server 2 and allows the following coin related tasks to be performed (with either bitcoin, litecoin or dogecoin): * Generation of new coin receiving address * Transfer of coins from the wallet to a given address * Checking how many coins a given receiving address has received and how many verifications does the transaction have. In case the receiving address has received more than one transaction, the code must return an array with the information per transaction (number of coins, number of verifications of that transaction). The checking of receiving address balance must work in a way the server 2 calls a PHP code in server 1 after a transaction has occurred. Not, in a way that the server 1 periodically calls the server 2 to ask if transactions have occurred. You are free to use any free, ready made libraries and software available. If your solution relies to any such software, please let me know when making your bid so I know that your bid and your solution is based on such libraries/software.
