Instead of writing and publishing on a seperate blog, why not publish these posts on your own (main) site? This would increase number of pages in the SERPs, possible keywords to be found by, adds authority.
That "Authority" that onlneleben mentioned is very important nowadays, in my humble opinion.
If I were you, I would probably do something like this:
1) Look at the sites that are linking to your competitors, and determine what type of content they tend to link to.
2) Write UNIQUE content that you think would be of interest to them, AND of interest to your visitors.
3) Tell those sites about your content, and ask them if they would link to you.
Now, that's just one way to do it, but it has the advantage of getting you new content while getting the word out in front of people who are more likely to promote that content.
The thing is, without much money for promotion, for every one hour you spend on content development, you will probably have to spend four hours trying to get links to it.
Plus, it can be a little soul-crushing when you get an email back and they say that your content isn't good enough to be linked to. Nobody likes getting a rejection letter.
I hope this helps.
