decompiler program for metatrader ex4 files

I would like a decompiler program for metatrader ex4 files. The ex4 files should be decompiled to mq4 format. The mq4 language is very similar to C language and any experienced C/C++ or java programmers should be at ease with the language. The program should take any ex4 file and convert it back into mq4 format. I would be prepared to pay between $50 to $150 for the finished program. More about the Mq4 language, the compiler and metatrader can be found at [login to view URL] I will only pay for a working program so no time wasters please. I'll send you a .ex file and you can then send me the mq4.
