For a funded gaming startup that is about to launch a social-mobile game, would you suggest to self-publish or go for a publishing deal?

We are angel-backed gaming company, and our first title is about to be launched soon. We've iterated the game for several months and we are about to achieve very good numbers regarding retention, virality and monetization. We estimate that in order to have an impact with this game, meaning create enough value (big enough revenues to self-sustain or big enough userbase to get the next round of investment), we need to reach our users fast, but we don't have the budget needed to achieve this alone (People say that we need at least $100K to get somewhere in the stores). So we have started approaching and negotiating with game publishers. Any thoughts? Do you think that even in our situation there is a way to successfully self-publish the game, or would you advice to establish a partnership with a publisher? Thanks,
