Need Two Pokemon Altered

[Cheesy Demon]

I need my Landorus and Latias altered for my team.  Latias needs a Timid nature and IVs in everything but attack, and Landorus needs a Jolly nature with everything but Sp. Attack.

I can offer a Snivy, Fletchling, and Tepig with their rare abilities and commonly used natures.
