You got it relatively easy: I assume you don't have any good contacts on the business, which is the obvious first choice. You can find clients at upwork or some freelancing site. Prioritize portfolio building and long term projects/recurring clients over one time deals and money. After a trial period, if you are good and trustworthy enough, ditch upwork and start charging them what you are really worth. Obviously don't be a dick and be upfront about your intentions of charging them more when you prove them you are worth it. It is a lengthy process. You need to be reliable and smart, otherwise you will not find good clients and you'll be taken advantage of. I don't want to discourage you but if you aren't good enough yet and you need the money now you'll be better off working at mcdonalds or some other simple teenage job.
