prlog.net is a great website for press releases. I recently had a question about press releases I had answered (You'll have to check the topics I've started to find it, I can't manage to find the link at the moment) about press releases and how to properly use them. The gist is that if you can offer a unique piece of content or service and you write a catchy press release and get it published, you can have loads of traffic to your website.
Try to get more google backlinks, page rank will improve, and don't be discouraged. Keep working and one day you will be able to achieve your goal.
