digixmas has a decent article submitter and directory submitter, but this obviously produces mediocre-low level quality links. It does have tools for checking the submission and outputting the exact url of the link, so that you can use services like linklicious or other indexing/spidering services to expedite google's finding these links. The results range from 0-38 PA in OSE. Obviously using these tools won't get you ranked in highly competitive niches, however you could probably achieve top 10 in somewhat competitive local results such as 'industry + cityname". If you're going to use these tools, i would strongly recommend using the submission report features I mentioned otherwise your links will not be spidered for a LONG time.
