[Nassau] Need help changing thermostat & water pump: 2010 Scion TC

Hi everyone! I'm located in Callahan off Ratliff rd & I was wondering if anyone in here is nearby & willing to help me change out my thermostat & water pump on my car, it's overheating badly and I don't want to blow it up or I have no way to work.

I have the new parts, I'm just scared to do it myself bc I really have no idea what I'm doing. I called a mobile mechanic who quoted me $300 to do both, but I'm behind on rent atm from not being able to work since the car is overheating- I can't even get out of my neighborhood without the temp gauge needle topping out so I'm scared to drive it.

My brother has helped me with stuff before like change the valve cover gasket & spark plugs but he isn't a mechanic so he said he doesn't feel comfortable doing these parts, which I understand totally, and I've asked everyone I know for help with no luck, so I thought I'd ask here and hope for a miracle. I have literally $6 to my name atm bc the car has been doing this since just after Christmas & I spent the last of what I had on the new thermostat, water pump, and new coolant since I know it has to be drained to replace them.

I have another job lined up but I need the car to be in good shape before I can get hired, and I plan to look into Uber eats/Doordash as well once it's running smoothly again. I can ask to borrow some cash from my brother for gas money or a case of beers (if you're 21+ ofc), but I'm also willing to give my last $6 and pay more once I get back to working, since all I need is to fix the overheating issue and I'll be golden again.

If anyone can help, you'd be a real lifesaver!
