Kick starter is great, but there are several other sources.
1) donations! Yes, some people have hearts. Start a blog/site of your game and ask for funding through donations. This is also vital for advertising.
2) upload demos of your game all over the web. Is it a flash game? Try kong, moshi, or others. I have had great success on kongregate.com you upload your games and get paid for views. In your demo you can have an option to donate.
3) Steam! Make a alpha stage project and have people buy a "demo" of your game with the promise of giving a completed project at completion. Very similar to steam, but even harder to do. Make sure to present your game well.
4) Run google ads or epicgameads in your game demo. Run them on your site too. I hate google as of the moment as they so ban accounts for no reason.
The bottom line is that you can do a lot to generate some income for a game. However, you used the term "indie" game. Back in the day I would think of a game under 5000, but some indie games rival that of the big wigs themselves. I would again encourage against not trying kick starter. I was fully funded through them (though only a 100 bucks) I would be happy to talk to you more about this subject via phone. I also make games, mainly flash, so I think I could talk about how I got funded. I hope one of the methods above will give you an idea of what to do.
There is indiegogo, which has good traffic, as well as Gambitious, which will veto applications, and also lab.gamesplanet.com
I recommend taking a close look at Kickstarter though. It's the best for indie game developers, even if you hve to go through a US payement agent if you are not in the US
