LF: Specific Mega Stones

[item] I'm looking for specific Mega Stones, particularly the X-exclusive ones. Here are the ones I'm looking for:

• Charizardite X
• Manectrite
• Tyranitarite
• Pinsirite

I am trying to collect the Mega Stones so all I can offer in return are Pokémon, preferably 4-6 IV breedable Pokémon that are accessible in Y. For those that are interested, please tell me what you want in return for the stone and I should have your Pokémon ready within a day.
