From my experience, crowdfunding is hardly/if-ever effective as an actual fundraising tool for the vast majority of entrepreneurs (particularly if there are actual goods being manufactured and delivered.) But what it can be used for effectively is a tool to gauge and show interest in your business product/service. So if you can get people to participate at a certain level you can take those "pre-sales" to your potential investors and show some level of possible market validation or interest. so I'd leverage crowdfunding more for that "community interest" piece, rather than actual funds being raised.
