A lot of Home Depot's have hand saws in store you can use though I dont know about NYC

I live in a tiny apartment and bought a hand saw (like $10 maybe?), used a ceramic plant container as a workbench (cut over the hole in the middle so I didn't saw through my work surface, it also collects sawdust) and just hand sawed a bunch of stuff. Hand sawing sucks and takes forever but for your needs it's manageable tho may be 3hours or work or so :)
