Maybe offer a limited time only promotion on your paperclips that is so good people will want to share it (ok so I'm clasping at straws now but you can see what I'm getting at).
How about a "For every paper clip you buy, we will donate a paperclip to a child in Africa" campaing ;)
Seriously, if you are able to set up a cause, then you can get some free promotion - and links. Can you donate any thing to fundraiser events so that you can get a link?
I do not want a crappy link on one page, I want a nice sitewide. Will 50$ a month do?
Well, yes, you can buy links. But another thing you can do is help out with free SEO advice / services for sites that are related to yours in exchange for a link. It would have the benefit of as that site ranks better and gets more links (due to the free SEO help you gave them), that site will pass more page rank through the link back to your site.
