Need advice on what i can do for money online

Hi, im 18 years old and i need a way to make some extra cash. Im going to be getting a car soon so i need some money to help pay for the insurance and fuel costs. Whilst i would just work a normal part time job, the problem is my college hours. Im usually in from 9-4, monday to friday, which means that i dont have alot of time after college so it might not be possible to work a normal job. Aswell as that, there arent many places near me that are hiring.

​

Ive seen some posts about rating services such as Lionbride and Appen. Im just wondering, are they legit? and is it something i can do for like an hour or 2 a day after college for some extra cash?

​

Thanks
