Scott, Robert is right about creating a handful of niche mini-sites. There are a number of benefits in doing so, one of which is that dreaded sales killer, "distraction--too much information!"
By creating these mini-sites you really now only give your visitor two options. Buy (take action) or leave. Both my newsletter sites are mini-sales sites with the ONLY intention of getting the visitor to opt-in. There is no distraction, and hence if the visitor doesn't opt-in, they probably aren't the subscriber I want anyway.
My 1 page eBay newsletter mini-site was #2 on Google for many months... however Google have now done something funky and it's nowhere to be seen
But that's my problem
Think about it--you would be able to have highly targeted keywords in AdWords, combined with a very specific AdWord ad directing prospects to your highly focused mini-site. Make sure the mini-site answers their question(s), solves their problem(s), and generating sales will be inevitable.
Not only that, but from your generic root domain, simple create a site map for the SE's to crawl. Won't it be a pleasant surprise when your mini-sites start popping up on Google page one

Take care,
