If I understand what I'm reading on the Elive website, the latest (current) version of this thing can be downloaded and used Live, without cost. Using it Live should be adequate for evaluation purposes, perhaps even enough to write an article about Elive and earn yourself an invite all on your own. See here:
and of course, the Payment Options section here:
If you don't want to pay for something that costs money, and are not inclined to earn yourself an invite for it fair and square, I don't see why anyone else should or would want to send you the invite that they worked for or paid for.
There are other means besides IRC to contact Elive as well. Perhaps you can make some headway by using another means, like email. See here:
Finally - see post #2 above. Looks like a good option.
