I need to make money for my build quick

So im 15 and ive decided to build my own pc for school and gaming. My buildis $1650 which includes everything since the only thing i will buy that isnt on that list is a $35 overwatch extended mousepad from razer.

So my point is this summer like the past 3 summers im not travelling anywhere so to keep me busy and so i can learn how to build one i can get a pc. But the problem is i need to make the money fast like 2-3 month period fast. I already have saved $408. But i was wondering if you guys knew any ways to make money fast as a teenager considering i live in Dubai ( And yes i have converted all the prices to USD for the majortiy.) And that most people already have maids or tutors and i am trying to sell everything i can and whatever else i can find in the house.

P.S: Im going to bed now so i will read and respond to all comments when i wake up. All comments are appreciated thanks!
