I do and I respect the amount of work you have put in already and the commitment to your project.
My point is you will be surprised at what you can accomplish on your own and given the choice of not moving forward because you don’t have the money to get specific narration or getting narration that is good enough, which are you going to choose?
If your goal is make more films then the most important thing is completing this one as quickly as possible and taking what you have learnt to the next project so that one is better.
I looked at your project online. You have an interesting topic, character (likable?) and good access but you need to think about putting a shorter fundraising trailer together. The work by Fernanda Rossi is a good place to start.
Good luck with your project.
