Looking for a possible autoblogging solution..

Ok. Im a cabbie in Boston and I have the domain names for most of the Boston neighborhoods. My main goal is to own the SERPS for Boston related searches. A little adsense income that I do get helps offset the huge cost of buying 50 .com names every year and hosting etc.

I have WP installed and up and running on all my sites. Complete list here http://southiecab.com/linkz.html

Im familiar with SEO.. I get the general principles about it anyway. Inbound linkz..as many as possible pretty much sums it up.

The one thing I need is content.. cheap content at that. I cant afford to pay people to write articles.. I'm looking for an autoblogging solution that will put out pages good enough for the SERPS to cache. I honestly do not care if anyone ever reads them or if they can be understood I just need unique content that will bring in visitors who will pick up a phone and call a cab.

SEO is almost useless if the SERPS have nothing to cache right?

Yes, I know this thread is quite old already, but the idea behind it is quite interesting.
If you try putting local search terms into the AdWords tool, you'll see that they get a higher CPC than non-local ones
and are of course easier to rank...
