Crowdfunding is a great way to raise funds.
I do, however, recommend having a back-up option for self-publishing your book. I had an unsuccessful crowdfunding campaign on Pozible in 2015. I raised 26% of my $15000 goal amount and I learnt so much from that experience.

Friendly FYI…these tips are from a 2016 video series I filmed after self-publishing a children’s book in Australia. Find all 20 videos on TAKU TV at https://www.youtube.com/playlist?list=PLc-QE_S9GwVCh40ZavHMT39zvwVnosazY. (Tips start at 2:00 in the podcast episodes).
