Looking for at least 1 bedroom (or roommate), starting July

I have recently been hired by a school near by and am looking for a place to live to move into in July. Every apartment complex within 45 minutes is completely full, so I need to find something else. I am a 23 year old single woman, however I have a dog, so wherever I live must allow dogs. I am open to roommate situations as well, and am trying to stick to 1200 a month or lower.
