You may have noticed a trend among many of my posts relating to the Festival: I have practically a $0 budget to work with. Perhaps in upcoming years I can work on that, but being the first time in this position I'm doing whatever I can to stick to the current "budget".
I did some research this morning, and here's what I came up with; hopefully it saves you some time.
CauseVox - free until we hit $5000/month in donations then switch to monthly (http://www.causevox.com/pricing/). Site is quite professional and gets my vote. Would appreciate people taking a quick look at others on the list to compare, though.
Indiegogo - although we don't get the benefits of being non-profit (only applies to US ones). Fees depend on which option you choose. (http://www.indiegogo.com/how-pricing-works-on-indiegogo)
FundRazr - We qualify for "lower fees" under non-profit (http://support.fundrazr.com/hc/en-us/articles/200055273-Can-I-Raise-Money-For-Charity) but I can't find exactly how much lower. Ensure your PayPal account is registered as a Non-Profit. (https://fundrazr.com/pages/service-fees)
Haricot - A possibility. Based in QC. 5% fees (http://www.haricot.ca/page/how-it-works)
Fundo - Also from QC. Feeds depend on which option you choose (https://fundo.ca/en/home/pricing)
Fonpop - Also from QC. Can't tell if there any fees involved. (http://www.fonpop.com/en/faq.html)
Weeve - totally free, but not sure what "Acquired by LX Ventures" might mean (http://www.weeve.it/landing)
TrendTrunk - very different way of fundraising (https://www.trendtrunk.com/fundraising)
GreedyGiver - If we had stuff to give away... (http://www.greedygiver.com/FAQ.php)
MotherlandFund - Site looks terrible. Fees are nothing special either (http://www.motherlandfund.com/pages/how-it-works)
Ones we can ignore
Kickstarter - not for non-profits or donations. Must be creating something
Giveffect - only for Charities
Catalyst - only for "social change"
Legup.ca - looks very low-budget and doesn't appear to work for organizations yet
ideacious - only for products
