My suggestion is that you read this article and then implement it.
Most likely, yes. bigup401 has a long trail of abusing perlmonks as a free (as in beer) code writing service. To me, it looks like a single job rotating around a multi-language web application that needs to mail some stuff and use the Paypal API, accepted by someone who has not the slightest idea of how all of that could ever work. bigup401 has proven several times to be unwilling to learn, unwilling to answer questions, unwilling to show a minimum of efford when writing postings. For me, it's just a waste of time to answer postings of bigup401. That time is better spend answering questions of people showing at least a tiny bit of effort, and are willing to learn just a tiny bit.
