Will work for traction

In the last 6 months our team has shoestringed a bookmarking tool for power users. The project is stable beta, but now we have a problem:

0. No connections in the valley. 1. No money for advertising. 2. Both of us are introverts. Unfortunately this excludes social promotion.

We are looking to make a project for you in the next 3 to 24 months and we'd like to have publicity for our project in return.
