shoot, man, you got your work cut out for you. 
but, I was about to suggest something along the lines of what R suggested.
Iād even go by a check list:
1.) Manufacturability and functionality through good coverage of griptape(probably the most important)
2.) Originality (may be the most time consuming judging criteria)
3.) Pop (how does it appeal to you from a graphic perspective, usually a strong yes or no answer, itās an āehā thatās probably a no)
Thereās about 15-20 images per page. If you can answer those 3 questions in less than 15 seconds per submission (5 second for each question), that would equate to around 300 seconds per page or only 5 minutes. Theoretically then, it should only take around an hour or so to go through everything to include documenting your answers. Thatās basically 2 half-hour tv shows you might have to give up if you watch tv if you do it all at once. It might be better just to do it in chunks.
While it may seem daunting, itās not as bad as it seems because some submissions should be faster to answer than others which will help your decision making process.
If it helps any, I think Iām about to burn out. LoL!
