We created our own press release and posted on the popular web hosting forums like gsprating, gsptalk, web hosting talk etc. I would also suggest posting your press release on a few social networks and having a page attached on your website for such announcements. Something I need to add myself.
You can have one written and distribute to the major network. there are many services like that in this forum and other forums
You can get some good results with press releases, imagine having your press release for a considerable amount of time on Google News, unfortunately the best ones are not free
In terms of submission, I've always had good luck with PRWeb.com. They have a great distribution range.
