It's so easy to fix up too. I can do it myself without help in a few hours. Then a few more hours to fix up the tier, lay out a tier addition plan. The lay out a PR campaign and strategy by drumming up attention on major gaming communities and jumping on a ton of different podcasts if possible.
Take all of that and re-do your introduction video telling people about the game. I could probably have a rough outline done in a day of what you should be saying, then you would just have to reshoot it. Maybe a day or two for post production.
Then once the majority of that is done (hopefully by mid next week) do a media attention grabber, do a newsletter to current backers asking for help spreading the word.
Done. It's all about format, fonts, and the proper look to give it a professional shine. You just need to know what to do and have someone with some good photoshop skills.
