Need Help with Custom Cavalier Order

[Maidhc O Casain]

Hi there! I'm trying to code the Order of the Chimera from Louis Porter, Jr. I used to be able to cobble things together sort of well, but it's always taken me forever to do. I'm now at a place in my life where I just don't have that much time anymore. I've gotten the very basic bits of the order done (the class skills and free feat), but I no longer know how to do the abilities that are added as the character levels up. Is there someone on the forums with a little bit of spare time who'd consider coding these for me? Here are the abilities I need:

Order Abilities: A cavalier that belongs to the Order of the Chimera gains the following abilities as he increases in level:

1. At 2nd level, the cavalier adds one-half his class levels (rounding down) to his summoner levels, but only to determine the base statistics of his eidolon. Spells known, spells per day, saving throw, base attack bonus, and other special abilities are unaffected.
2. At 8th level, the cavalier gains the Arcane Armor Training feat. If this feat is already known, then Arcane Armor Mastery is gained instead.
3. At 15th level, the cavalier gains the life bond summoner class feature.

I very much appreciate any help I can get!

PS: One of my missteps as I started this was saving a version of the Order with a unique id that I don't like. I changed the unique ID and saved it again, but now both versions show up in the list when I try to create a character, and the first one is available when I do a "New (Copy)" in the editor, even though it's not in the list of Custom Abilities in the editor. Anyone know how I can make it so that it doesn't appear in the list of Orders when I'm creating a character? Thanks.
