I'm copying here a quote from a forum entry by Nicola at ClassicalCrossover.co.uk
"Go to indiegogo, kickstarter or pledgemusic.com for donations from fans. Many indie artists do this and fans are immensely happy to do it; to feel part of the album making process.
Here's an example of Jonathan Ansell's: http://www.pledgemusic.com/projects/jonathanansell?utm_campaign=project4042&utm_medium=project_badge&utm_source=unknown"
I have also been impressed by Siobhan's here:

You'll have my support - guaranteed!
