Looking for My Little Pony OCs

I'm working on a MLP:FiM fan-fic called The Tale of Lovely Feathers and am in need of some background OCs for a couple of chapters. To see the story so far and get an idea of what your character would be in, here's the link www.fimfiction.net/story/14999…

Here is a list of pony types that I would REALLY like to have (also, in exchange for borrowing your OC in my story, I'll draw them )

Unicorn filly (school-age)
Earth pony filly (school-age)
At least two (2) stallions : Unicorn, Pegasus, or Earth Pony (palace guard position)
At least one (1) mare : Unicorn, Pegasus, or Earth Pony (palace guard position)
At least two (2) MAX six (6) mares : Design-related talents (dresses, decorating, etc.)
Pegasus stallion (will be father to my OC Silver Flight [grey pegasus colt]) Preferably palace guard
Unicorn/Earth Pony mare : Medical-related talent

Please put a link in the comments below of your OC. If you have an OC that doesn't fit in the list above, you can still suggest them and I may find a place for them. Note: This story takes place 40 years BEFORE the events of The Mane Six, so children or relatives of Twilight and friends will probably not be accepted.
