There is a ton of information on crowdfunding all over the web, including online courses, some free, at Udemy.com. There are all kinds of metrics that are quoted at this point given the millions that have been raised.
After researching( and still researching now) the interesting thing I found is that the success depends on a) prep and b) the experience. Too much to go over but I would suggest you go to Udemy and take some courses. Secondly there is a website run by a kickstarter "expert" who does post campaign interviews to find out what went right and what went wrong. (http://artofthekickstart.com/)
There are also crowdfunding "meetups" in many cities now that dig into metrics, landing pages, and a host of other issues tied to success.
Crowdfunding, as with outside investors, fails more often than not. It may take 3 months of prep to finally actually launch, so you are looking at 4 months minimum, assuming a 30 day campaign.
I will say this - it is a heck of an experience and you will learn, even just during your research, of many tools and techniques that are very cool and very useful regarding the mechanics of planning, pre-launch, launch and post-launch of your campaign. It is a lot of work and most who have a day job end up working 14 hour days until the launch is over. No short cut here unless you hire outside help to take some of the social media pre-launch/launch tasks off your plate.
