I hope this thread is still open.
I was considering building a wordpress based crowdfunding website using PageLines or HeadWay as framework. The difference is that supporters would contribute by SMS .
HeadWay and PageLines allow for unlimited modules positions which in my opinion is great feature for cloning an existing website. In addition they are responsive.
I am not a programmer but managed to create more or less the same layout as kickstarter while manipulating HeadWay. So, I guess a coder could use any of these 2 tools to build up a wordpress crowdfunding website.
Anyone interested can contact me.
