The Google Page rank (which i know everyone says ignore) is zero - although i know i am supposed to ignore it, could this be the reason for the low ranking?

Google PageRank is being updated constantly. Google Toolbar PageRank (TBPR), though, which is what you see, is generally only updated every few months. I think it's been a while since there's been a major update, but in fact I really haven't paid that much attention to the "schedule". The effects of actual PageRank, though, should be observable before you've seen the green bar move... and PageRank, together with associated trust factors, etc, is a ranking factor, probably not what it was a year ago or five years ago, but important in a variety of ways.

We are still ranking very low for the keywords we are targeting.

piatkow describes the kinds of expectations you ought to have, with the caveat that a lot depends on things like inbound link quality and appropriateness, how good your content is, and how well you've optimized and promoted your site.

Here's a discussion that doesn't address your question directly in terms of numbers, but the topic is strongly related to your question and you definitely should read it....

Does Google "Age" Your Backlinks?

How old is your site, btw... and, more to the point, how old or new are your backlinks? Is your content unique? Has Google crawled and indexed your main pages? How big is your site? Etc etc etc.
