Need some advice for my side-hustle startup idea

[AbuHossam]

I’m a junior in college studying Finance. I’d like to start a little “Social Media Management” business here in my college town. I think there are some small businesses here (especially some of the bars) that could really benefit from having a college student manage their social media and advertising. I’m pretty knowledgeable about all the major social media networks, and I’ve even been working on building my own website/blog recently.

1) how do I reach out to these small businesses and convince them that I would be an asset for their team? I’m not sure some business owners would find a lot of credibility in a freelance college student

2) how do I charge them if they do decide to hire me? I don’t think I should charge hourly because I’m a pretty fast worker. Should I charge a weekly/monthly amount?

3) do you think I need more education on the topic? Where would you suggest I learn more?

Any experts in this field?
