rissa: where i can find PR5-7 backlinks for free?

you can search in Google or any other search engine for this....

You can always search around for lists of high PR forums and then manually create an account and make a few posts and of course add your links into the profile/signature.

Won't take long and it's completely free.

What you can do is make contextual backlinks where it does PR 5 or higher

I recommend you tumblr or blog comments. This are a good source of high pr backlinks. If you want to scrape a lot of links and check PR you should use tools like scrapebox. After this you can just manually insert your backlink on the high PR page.

try searching in google

go to search engines like google,yahoo,msdn,babylon,etc
