looking at your previous questions on hackernews, i now doubt whether you are asking all these questions just to drive traffic to brightjourney ?

If your current revenue is the result of minimal / no advertising then why not try allocation a little more funds there and see the results.

Is there any scope for improvement to your product other than bug fixes ?

10x annual revenue I think flies by many investors books and wouldn't seem "outlandish". If need be you could probably meet somewhere in-between 5 and 10x. 2x seems like too low of a multiple.
