Most bank managers in my experience do not know games, and your chances of getting funding from them without a great track record is probably close to zero. But there is another way. Kickstarter.com
is the world's largest funding platform for creative projects and that includes games. It's a community of people interested enough to invest in worthwhile projects and the people with projects that need capital. Of course not every project gets funded but the core principle is All or nothing
funding. You set an amount that you need to fund your project and a deadline. If you get enough people pledging by the deadline then you receive the money. If enough don't pledge to give you 100%, then you receive nothing. It's not just for game funding but covers many areas: art, comics, dance, fashion, film, book publishing, video, music, photography, technology, etc. Some projects get massively over funded while others don't make the target. Backers vote with their wallets. There's no set amount that you must invest but usually a set of investment levels and corresponding rewards are decided by the project founder. The more investors put in, the better the reward, something like invest $1 and you get a thanks, $5 for a mention, $25 for a box set, $150 for a years free gaming and for $5,000, you'll get game features named after you, etc. Each level also gets the rewards from the lower levels.
