I just had a few questions. Is there anyway to level up quickly in sun and moon since it seems very tedious without blissey bases? Also, where can people get animated sprites for the gen 7 pokemon, I know where to get it for all the other gens but not for gen 7?
As for leveling up quickly, most people agree grinding at Poni Gauntlet is your best option until Lvl 63 (Or is it 66? I cant remember :P don't quote me on that). Slap on a Lucky Egg and just keep battling. Then, you can use the Rare Kitchen method to get up to 98. This guide explains it better
here.
Going off what Nelson said, Showdown also has its models exportable, and while they aren't as organized, just use Ctrl-F :P
This is for normal models
This is for shiny models
If you're looking for the actual small sprites people make for each Pokemon, there's not really a good site for that (or at least one that is complete). I honestly just rip them from Serebii. If you go to the Pokemon you want on the Gen 7 Dex, then go to a Dex entry behind or ahead of the one you want, if you look at the move forward or back section at the bottom of the right toolbar, you'll see a small sprite for the Pokemon you're looking for. I just steal it from there, beacuse Serebii is reliable and they have them all :3.
