I believe he is simply looking for new ideas; he notes that he is having " MOCer's block".
However, I for one don't have A) a white pakari and B) the time to devote to this.
Also, C) there is no prize and thus not much of an incentive to do so. Time is very limited for a MOCer like myself who is balancing college classes and stuff, and even then I don't have a job so I have more free time than most.
TL;DR I would recommend making your own MOCs since I don't think you'll get many takers.
