I agree with all of the comments here and would also like to add that we should have factored into our budget additional advertising and promotion costs.
It's great to be contacted by companies who can help with this - particularly when you are a twitter novice - however starting costs of $600 are a shock, especially if you cannot be guaranteed you will get your funding!
I am also still navigating twitter etiquette and how to get people to follow you and hopefully retweet your posts. I haven't been too successful with that!
There is far more preparation than just the Kickstarter story, budget and photos to get the campaign going.
