Well here are the shinies I can offer:
Beautifly, lv14, careful nature, hates to lose
Gliscor, lv50, naughty nature, quick tempered (possibly hacked)
Tentacool, lv23, naughty nature, highly curious, UT
Banette, lv37, calm nature, somewhat vain
Ditto, lv76, naughty nature, scatters things often
Sableye, lv53, bold nature, hates to lose
And some of my non-shinies:
Zapdos, lv60, Adamant nature, highly curious
Zapdos, lv50, naughty nature, strongly defiant
Mewtwo, lv80, jolly nature, likes to run
Rayquaza, lv73, rash nature, highly persistent
Rayquaza, lv75, calm nature, loves to eat
Groudon, lv70, adamant nature, quick to flee
None of them are great, but they're all I've got. I can offer Feebas, Spritomb and any non-Johto starter, but for you'd probably find a better deal for those on the GTS
