I wouldn't necessarily try to crowdfund for a YouTube channel, I'm not trying to be mean or anything but you should start off your channel to have fun making videos and get better at making them in the process. I get that you may feel that you need better equipment to compete with other channels but, that's not necessarily the case. People will find you and support you if you entertain them. You must treat YouTube as a hobby first and if you're lucky enough it may just turn into a job or an extra source of income. Also, it's going to be difficult for you to crowdfund a YouTube channel as 1. Not many people know about your channel & 2. I've never heard of a YouTube channel being crowdfunded? Everyone has to start somewhere so my advice would be, be consistent and just have fun with YouTube!
