Decompiling of an EA

Hello, I need the assistance of an MQ4 programmer to decompile an EA for me. I need to review the code, but I only have the ex4 file. The decompilers that I have found will decompile the file, but it will lose the variable names. I need someone who can decompile the ex4 and return to me a working mq4 file that has everything there, including the variable names, etc. The EA does not use any DLLs or external files as protection. I need someone with experience in MQ4 , preference will be given to programmers with positive feedback. Thanks
