Pet Care Needed - Full-time / Part-time

I have a semi feral kitten. She normally doesn't attack humans and she's actually pretty friendly. We picked her up off the street a couple months ago and unfortunately we cant seem to get her to behave around other cats in which she constantly chases with intent to attack not playfully. I don't want to give her up as I love her so much so I'm trying to find someone to help me make the cat friendlier around other cats.
