Is anyone giving away/selling a dog?

i had an australian shepard named luke who was 14 years old and my parents have had him before i was even born. he eventually ped away from cancer and we have been devestated. we are look for a dog who is 5 years old or younger that is NOT a pit bull, boxer, or hound dog. here are some stuff we are looking for. (u can show other stuff too) we want a medium sized dog so that we can take the dog pretty much anywhere, a dog that likes to run and i very playfull, 5 years or younger, female but male is OK too, mostly looking for an ozzie, is good with other dogs, is spayed/nuetered and has all their shots, good with kids and grown ups, and is 100 dollars or less. we are good owners and spend lots of time with our animals. give me a link or website name. THANKS!!!!!!!!
