I can only think of a few publications off the top of my head that continued for at least 9 issues, so our's could definitely be what you're thinking of.
The comic is called
The Agencies and takes place in the greater Seattle area, in the near future. The web site is
http://www.the-agencies.com. Agencies are collections of mercenaries, most of whom have modest super powers they use throughout the stories. And most of whom are indeed female.
We have ten issues available to purchase as of today. The main storyline starts with issue seven (go to
http://www.the-agencies.com/agencies/issue_seven.htm to see it), while earlier issues were just standalone stories. We haven't had a release since August 2006, so we're about due!
Issue 11 is currently in production, and I'm really excited about it. I know, by law, I"m required to say that about every issue, but issue 11 will be almost as innovative as issue seven was for the series. So I'm looking forward to bringing that up to publish. There's a reason it took so long to produce, and I'm pleased with it so far.
So if this what you're looking for, hit me with any questions you have.
