Best ways to find homes - ideas?

I have had three more animals 'dumped' on me...

1. Black GSD mix, maybe 2 years old, and hyper
2. Black unknown dog, probably 4-8yrs old, HW positive :-(
3. Calico kitty who just had 4 kittens (they were taken by someone else)

I need to find homes for these guys - I have 6 dogs of my own, 3 cats, 3 birds and a turtle... oh and Im single with no one else in the house to help out... food is getting crazy and I think I am starting to loose my mind too, heheheh well not yet...

Anyone have ideas for going about finding homes? The one that worries me the most is the HW positive older guy... I have posted on craigs list and done some posting. Im looking for other ideas that have worked for anyone else or creative ways to get potential adoptive parents attention... I have contacted a few rescues - they seem over whelmed and are not even replying to me (well I am not threatening to send them to the shelter now if I don't find a home - and honestly couldn't find it in my heart to do so)... times are tough for everyone and it is frustrating that animals are being dumped on me when I can't afford the ones I have but people know Im a good person when it comes to animals. Im just not very good at this placing and finding good homes and any help, anywhere would be greatly appreciated! appreciate your reading my rants as well.

Thanks!
