EV Training Help

[ceremony]

okay, so here's the deal.

i have a team, and i thought "hey, since i have the footprint ribbon thing, that must mean that if i train them, they're grow and get the max points they can get" but then i'm clicking around youtube videos on here, and i find that one dude, after growing a level, gained 29 points in speed. the highest i've seen for one in my game is 6. and his level 100 Electivire's HP was 100+ points more than my level 90 guy.

so here's what i need...i need to know who to fight, where to fight, and what items they need to hold (i had the pokerus, and macho brass doesnt do much in my opinion) to gain the most they could get. this is my in-game team so far:
