Mmmm.......you're interested in the maid/s being the focus, eh? Not just a maid (and yeah, a real maid is what I mean, not a cosplayer or whatever) being a character, is that right?
Mmm...yeah, if that's the case I probably don't have much......Shitsuji Shoujo to Ojou-sama probably fits that, maybe Majo to Houki to Kurobuchi Megane and The Voynich Hotel? Shounen Maid probably fits but its scanlation efforts are dead........
anime I guess I'd suggest Kimi ga Aruji de Shitsuji ga Ore de ........I think I remember it (fairly) seriously revolving around maid/s
