Why are you starting out cold when you are working in corporate and have all these connections? You should set up a business (doesn't cost much) and then start asking clients if they need a consultant offering the services you want to offer.
Don't even need to quit your job.
Lmao, you are severely underpaid. You are pretty much doing the job of multiple people. $800 a month and they want to cut prices.
Just imagine a full time social media account manager making $60k/year with benefits. You are making & 9.6k/year with no benefits and doing way more work than them. They probably need 2 people to do what you are doing.
