Continue reading this forum, search and read all you can about SEO. Even with money, it is very difficult to rank well - without it, it will take even longer and will take more knowledge on your part.
I advise that you start off by studying narrow topics in SEO separately, so that you don't get overwhelmed.

Here's a list tof basic topics to start: optimizing meta tags, optimizing header tags, SEO copywriting, creating compelling titles, directory submissions, article submissions (syndication), blogging (blog and ping), link exchanges etc. etc.

There's only one way to increase your page rank and that's by getting more links (preferably one-way links from relevant sites), not including (known) paid links.

Of course there are many ways to get more links... search the forum for linkbaiting ideas and good luck

You can increase your PR if your blog is very important to it's users. If it is very important, you get many links, which in turn increase your PR.

My main point is:
excellent blog content for your target visitors + inbound links = Good PR

Read more about page rank found in this forum, you will learn many things.

gotta prioritize one-way related/relevant links

right emerson well said..

just continue your process and add more effort in increasing your BL, and also be aware in producing quality content on your site.

And as page rank is logarithmic, you only need to get about ten times as many links as you have just now...

Why is it ten times? Can you elaborate. Thanks.

You can increase your page ranks with back links by offering visitors some valuable tools @ one back link per tool. You may also run some contest for a big price and set the condition for all participant that they must add your link on their site to participate in this contest. Published some news and articles that never published in past and add RSS feed option on your site for subscribers.

Because it is logarithmic. That means each step is a factor of ten bigger than the one below it.

In the same way that 20 decibels is ten times louder than 10 decibels and 30 decibels is ten times louder than 20 decibels, and thus 100 times louder than 10 decibels.

So in general as you go up each pagerank step you need about ten times as many backlinks as the previous step.
A page with a pagerank of 5 has about 10 times as many backlinks as one with a pagerank of 4 but it has about one tenth of the backlinks as one with PR6. But the pagerank formula doesn't just count the links, it also looks at the PR of the linking page, so I said "about" ten times more (assuming all linking sites have roughly the same PR, higher PR pages linking count for more ).

But as pagerank is only one of about 200 measurements that affect your final position in google, why get so concerned about increasing it, it is easier to increase some of the other things, sometimes with just a few minutes.

Yes I know but how do you know it is of base of ten and not six, seven or eight? Do you have supporting evidence?

You don't know that.
I meant to add that as the last line but got distracted and forgot. Sorry. I did emphasise the word "about" for that reason. And because the linking site's Pr counts as well.

But the original pagerank calculation is documented on-line somewhere, so I'll have a quick check on that.

EDIT
This page suggests base six, and mentions that the base has been speculated on a lot.

it also says
"The higher your PageRank, the less impact increasing numbers of incoming links will have "

Somewhere I once had a link to a page that simulated the calculation of PR based on the original formula (you can see the formula at Wikipedia as well as the above link) and that showed quite clearly that you need large increases in backlinks to move up each additional step in PR. But unfortunately I've lost it.

EDIT 2

suggests a factor of 7.8, but shows clearly logarithmic

Ok, thanks for that. If you have some new ideas about it, please share with us.

Get more one-way link from a high PR sites. Make sure that they are using "Dofollow" tag.
