PHP debugging & documentation

I have an emergency, I need some PHP debugging now so please do not bid unless (A.) you are available via AOL messenger or MSN messenger, and (B.) you can begin debugging immediately. I had another coder write a newsletter application for sending mass emails, and the bottom line is that I believe they are coding in such a way as to guarantee their further involvement by not documenting anything whatsoever. We tried using the application, and out of more than 500 records it failed to send to all but 4 email address records. This is unacceptable. IMPORTANT: I need someone who can correct the script WITHOUT re-sending the newsletter. Here's why this is important: subscribers will potentially be hammered with "test" sendings and we absolutely, absolutely cannot have that. It is imperative that this is understood. I appreciate your taking the time to read this bid. It shouldn't be too difficult a fix, I just want a documented explanation of what was wrong and how it was fixed afterward.
