How to start an e-commerce business on eBay and is $3k USD enough money to start it? If you are successful with the $3k USD, is it enough of an investment to be able to garner you enough profit on a weekly basis to be able to live off of?

I’m based in the USA. Plz help. I need this, e-commerce might just be my last chance, I might become homeless in a few months if I don’t do something to turn my life around and I’m turning to e-commerce for salvation, I don’t have any experience or E-commerce knowledge so any advise or instructions on how I should get started, would be much appreciated, thank you for taking the time to read my plea and thank you in advance for your help, I greatly appreciate it.
