Moving Options Within NYC

I currently live in Williamsburg, Brooklyn, and I’ve just signed a new lease for a studio apartment in Rego Park, Queens, starting next month. I have two carry-on bags, four boxes, and a PC to move.

What’s the best way to handle the move within NYC, considering I don’t own a car? Should I rent a U-Haul, book a vehicle through a service(AVIS), or is there a better option you’d recommend?
