My advice would be to get as much art as possible up on your book page. Even though Inkshares is a book kick starting site we are still very much visual creatures that respond positively to eye candy. That being said some thoughtful formatting of the text on your book page can make it pleasing to the eye and go a long way. Check out my books page. I get a lot of comments on its layout.

The most tried and true way of getting big numbers is to reach out to every individual in your circle directly. After that, it can be a big help to get an influential friend/family member or two to do some reaching out on your behalf.
There are dozens of other avenues to consider, but their success rate really depends on the individual. Some people are great at pitching to strangers in a coffee shop/comic book store. Other people are able to turn their twitter followers into buyers. Not many people are able to get press coverage, but those who have typically get some mileage from it. You know your skill sets and abilities best, so this is the time to test their limits.
Definitely check out the older posts on the goodreads forum, as there is a TON of advice on there from successfully funded authors.
