Why don't you arrange a crowdfunding in your local area where you are surrounded by the people you know and the people who know you? Trust me, fair thing would be not to go to newer people as they don't know you and so, trust issues will definitely be there and if you rather manage an exhibition sort of (obviously with the limited budget that you've got) and invite your local people who, you know, that they know you and trust you as well and you can make them understand your project very well, then you'll definitely get your investors among your local people. Mark my words, it's quite easy to talk to people's minds who know you very well rather than breaking your head off the wall while doing it with new guys.
Thank you for the advice, I will consider such an option.
