Looking to begin day trading in my spare time, looking for any advice to someone who's never done it

I was laid off from my job back in January and am the primary caregiver for my elderly father. I am fortunate to be in a safe longish-term financial position so as a result of having to care of my father, I am no longer working for the foreseeable future. However I would like to begin day trading with a personal account to see what kind of money I can make day to day / week to week / etc. Maybe this is an unrealistic goal but I'm just looking to make enough profit week to week to just support food and gas expenses, petty cash type stuff.

I've heard from others that Fidelty and E-Trade are good platforms to use for this because they have no fees on transactions. Is this correct? Or is there another platform I should use to make a trading account? Basically my plan is to take $5,000 of my money and see what I can do with it. If I can invest it wisely and make a profit off of it, that's great. If I do a poor job and lose it, then so be it, I'll take the loss and be done with it.

I'm just looking for any tips, advice, experience, etc. that others could offer. I'm especially interested in learning what kind of media I should watch/read to learn how companies and stocks are doing, to get ideas in what I should invest in that day.

Thank you in advance.

Edit: Thank you to the few people who actually provided helpful feedback.
