I would set up a product website, do the minimal SEO work and run an Adwords campaign going after the easiest segment of your market. The easiest being the segment of small businesses that has the biggest pain and thus the biggest need. If they are small business owners they aren't 'living' on the Internet like most techies. They don't use Twitter, Facebook, etc. If they are desparate enough they will use a search engine to find something. This will help kick start your marketing and it can be running while your at work.
