There are two good choices - Spacehive or Crowdfunder.
You are unlikely to get funding from any of the organisations, even the council, unless you are set up as a community group, and even then it is not something that is likely to happen, nice if it does, but rare so don’t bank on it.
Spacehive will want detail, they will want a discussion and they’ll want to know cost breakdowns, contingency, liability, written permissions and any other hoop they can find before they will go live, but they will also help - they’ll push it, and they’ll do what they can to approach funding organisations and they have a very high success rate.
Crowdfunder will ask far fewer questions and you send it live when you want to. They don’t do much for their cut, but in this instance I doubt you’ll need much help.
If you can think of a good reason to get more funding, then crowdfunder allows for a stretch target and for over-funding opportunities. They also allow you to choose (before you go live and then you stick to it) if you want to do an ‘all or nothing’ or ‘keep what you raise’ plan, whereas with Spacehive you can only apply for what you need, and if you fail to hit the target you get nothing.
Whatever you do, make sure you account for a loss of up to 12% on what you raise. The platform takes a cut, the card processing takes a cut, neither are as small as they look on the detail. On this front, an advantage with Spacehive is, and I’m a little sketchy on the detail, but I think this is right; that they build in their fees as the total rises so what you see is what you get, whereas with crowdfunder, they don’t count any fees as they go along, it all comes off at the end.
There are always stragglers too - you get 75-80% of your money about 5-10 days after it finishes, then a week later some more, then a week later some more. It depends how many of your donors have the required funds in their accounts at the time the thing ends, and if it ends unexpectedly early, then they may not have the money in that account at the time.
