To Pubslush or not to Pubslush?

So, as I stare at my manuscript for the second book in my Family Heritage series, and think about the other projects I want to finish in the next year or two; I wonder just how much I will need to invest in editing and cover design. I went rather cheaply on my first book and used the free templates from Createspace. I had a friend with an English lit degree do some editing/proofreading. My brother in law drew a picture that I used for the cover, which I was actually really happy with as it captured the image I wanted my readers to get of the main character. I am thinking moving forward that I need to hire some professional services to make it more marketable. I have seen posts about people using Pubslush and Kickstarter to raise funds for these services.

I am curious if anyone has any advice/thoughts they could leave in the comments. Even links back to your blog post about your experiences with either type of service would be appreciated.
