Link building - trial project

I am looking to build a relationship with a link building provider for several projects. I did a project a few months ago but none of the articles written and submitted have been indexed by Google so I am feeling I've wasted my money and time. I'm looking to start again with a new provider who can deliver quick results from web pages that have already been indexed by Google, PR 2 or above. I am looking for 10 links as a trial project. If you can deliver these in a sensible time frame we can move on to some bigger projects for the different websites I run. I will provide anchor text or short articles, which ever suits your way of working. However, I will not treat the project as complete until I can see all 10 links from pages with PR 2 or greater so please dont submit articles to non-indexed pages. I want all articles to be on english language websites and from Western European or US websites. I look forward to receiving your bid for this project. Ian
