When working on a film, i am usually the writer or a chose a script which can be made on a small budget. Especially being a student. I feel in order to make a project a successful when there is a deadline to work to you have to be realistic. So in order to achieve this a script has to be written with a setting, with props and with costumes that can be possible to create on a small budget.
For bigger projects there are many people willing to support an aspiring artist of many kinds. Online is particularly useful. https://www.gofundme.com/ is the most popular and preferred site to use. When promoting yourself on this site i found it useful to know that it is better to not mention you are a student. Why? Perhaps people don’t like students. The best way to describe oneself is as an Independent Film-maker and to not give too much away, links to previous projects are great as the person willing to give money can see what kind of thing they are helping with.
Another way of course is friends and family, small donations add up and they are always excited to see the finished piece. It is always important to thank the people who give. Whether it’s a shout out or a mention in the final credits, it goes a long way.
