Sara,
May I make a suggestion?? It sounds to me like the kittens are a bit feral. If you can get a cage to put them in to keep them confined, you might have a chance to socialize them.
The only way you're going to be able to get them used to people is by handling them alot. As long as they are loose and running around, it's very easy for them to avoid you.
Once they get used to being handled, the rest will be easy.
What I'd do when I had feral kittens that age is keep them confined in a cage and take them out, one by one. Most feral kittens will hiss and spit at you, and play on your fear of them. I never backed down. I first began by talking softly to them without making eye contact (eye contact is a threat). Lay on the floor at their level and whisper to them. Then try, after a while, to pet them. They may cower, hiss or spit, but you need to show them you aren't afraid of them. After that, try picking them up. If it's still a little difficult, try wrapping them up in a towel with just their heads exposed. Pet them, talking softly to them. Eventually they will come around.
Good luck in your quest to find wonderful homes for them.
