A good camera for a beauty guru?

So lately I've been thinking and I've decided. I watch these beauty gurus and they get paid a LOT so much it becomes they're career and they live they're life as a beauty guru. I love fashion and i want to be a beauty guru. I've ALWAYS came home after shopping and filmed a video on my iPhone but i always delete it. I just enjoy it so much! But if i make videos i want to start off good. I want to get a good camera and stick with it. When i watch beauty gurus i hate it when theirs bad quality. Does anyone know of a really good camera less then 500 dollars?

You can probably get a Canon 550D if you want to make films and take still photos too. That will be in your budget
