Complete and fix an existent ANTLR3 grammar

Hi, I am looking for someone who can complete and fix an existent ANTLR3 grammar for text log files which are obtained from an external program. Currently when this grammar is compiled creates Python code that can consume those log files and produces a Python dictionary. However, there are several cases which produce a halt on the files consumption, it is because of some non-treated characters and has to be avoided. Also in the current grammar there is a lack of cases to be treated. This grammar is a second version. First version, which will be provided, considered those cases that are not existent in current version. First version can be used to complete the second version. However it is desired that the delivered code is written like the second version (minimum changes for readability) and be improved where possible. I'll provide all mentioned code, ANTLR used version (3.1.3), the grammar (new and old) version, and several unit-tests to be passed to accept the task as finished. Thanks.
