How much is a PR5 web deisgn link worth

[Virtual Banker]

I have a web design site with solid PR5 -
I want to know how much it would be worth to people to pay for me to host an article (web/seo) of their on my site with 3 outbound of their outbound links

is there a monthly fee?
what is the going rate?

I think it depends on what terms it is ranked for and how high it is ranked in serps also.

So the actual PR # has no value in itself?
