How to get $3000 fast?

I agree with others on this too;

Sell some of your things at a pawn shop

Put some of your clothes/jewlery/unneeded furniture/ etc.. on ebay

Sell your car(s) and use a bike or take a bus for transportation

rent your upstairs/downstairs/extra space

cash in empty cans/bottles for money (depending on how much stuff you have it can be worth a lot!)

get some little jobs, babysitting, yardwork for your neighbors, maybe like a McDonalds job or something like that?? Im pretty sure you could be able to get a job as a hairwasher or something in a hair place, I know those are sort of like ‘kid’ jobs, but if you want all you can get, you should try it.

Yard sale, wash cars, walk dogs, pet sit

If you know how to play an intrument you can play outside a busy area, people may donate money

if your good with computars you can do a PC repair service.

Thats all I got, sorry, I wish you the best of luck, I dont think it will be fast but its possible!!
