My startup in 2008 spent 3 years in development limbo and never launched. My next one in 2011 launched with similar numbers to what you described here and we eventually scrapped it because we had no way to effectively promote it. We launched a new site in 2012 and we now have over 7 million unique visitors a month to our site and hundreds of partnerships with other services. The biggest change we made was focusing on building partnerships in the industry. We never went to any conferences or sales trips, everything was via email introductions. Try to find a way to make yourself useful to people who have distribution channels, at least that worked for our individual case anyhow.
