Bittrex is the only legitimate exchange out of several mentioned. Poloniex and Kraken are OK too, but good luck getting listed on them at such an early stage.

I believe Cryptopia and the some of the other questionable exchanges will list you if you pay a fee, but again it depends on what you ultimately want for the coin. Most of the people here seem to want it on any exchange so they can insta-dump their holdings and be off to the next pump and dump coin.

A very small minority of the users have stated what I also think you should be pursuing, that of further developing a website, a better implementation of the wallets, work on improving the block explorer, and generally growing the community. You also should be developing a road-map with key milestones so that people can see when progress is being made. I also have seen no mention of why we even need this coin and what unique benefits it provides the community other than simply another coin to mine and speculate on. A whitepaper or at least some type of vision statement for the coin and its future would probably go a long way, as long as it is legitimate and not just some BS statement.

Since you didn't really pre-mine many coins to sustain bounty's to fund promotions and advertising you are already at a disadvantage. You can try to solicit donations from early miners, but I suspect you will have limited success as I have already indicated I feel most of the miners are mainly interested in looking for the first exchange to quickly exit.
