mql 4 parser with antlr

I am looking for someone to create a custom mql 4 language parser using antlr and java (i can consider other tools if i get the same result).
The parser must validate the code it reads, verifying if the code follows the walking rules of the mql 4 language; the parser will read sources of a mql 4 project and output the exact mql 4 program that it reads in a single file; i need code of the parser to be clear and easily customizable since this will be the basic of a more complex tool.

Wi am expecting to have at the end of the task is the antlr lexer and parser and the source of the java scanner, + options to be run from command line.

If you feel up to this challenge, please submit your proposal for this project. Thanks in advance.
