Thats impressive. Would love to know how you went about promoting the website too. Did you do any SEO / link building / other kind of marketing?
- keyword research to know what people are looking for
- creating content that answers specifically to these keyword searches
- link building as in article marketing (ezinearticles, goarticles...) and guest posting on a few small business blogs (example: http://www.marketingbestpractices.com/marketing-articles/off...)
