Would agree with Rodrigo. The days of a startup pushing out a release where anyone cares are over. You need to research who you want to write about you and pitch directly... there's tons written on the subject.
Having said that, if you just want to put a release out there then you can either:
* Spend $1K and put it out on PR Newswire or Business Wire... low probability of success, but higher than alternatives
* Spend $5 on a Fiverr gig and pray.
I'd recommend saving your $1005 and do the research and direct pitching.
