Remote work - short term advice

I recently came into some really big expenses, someone shot my car (stray bullet, absolutely nothing to do with me), and I also got a greencard. I have a PhD in cognitive neuroscience and work as a researcher at a top-tier US university. My salary isn't enough to cover these expenses and I am struggling atm. I essentially need $1500 in the short-term.

I am hoping I could make a little extra money doing some work online. I have created a fiverr, upwork, and data annotation account. So far only my fiverr is active (the other two are still verifying my ID). The gigs I have posted are related to academic writing/proofreading.

Does anyone have any advice for 1) having people find my gigs and 2) any additional places I could post my services that might help me reach my goal faster. While I need $1500 in the short-term, I would like to carry through longer-term to supplement my savings.

Instacard and taskrabbit are not hiring currently in my city, I can't. currently do uber/doordash because my car needs repairs.
