Chipsets and charsets

[Muramasa]

Hi everyone. I'm Muramasa and I am attempting to create a game. I want to make sure that I have resources, however, in order to finish it. I know it's a bit long, but I can take them one at a time, and from various sources. If you have even just one, can you help me out? What I need right now is:

Hospital chipset
Airport chipset (mostly a runway for a spaceship or something to land on)
Restaurant (any kinds) chipset
Abandoned Warehouse chipset (one with that sliding metal garage-like door if possible)

Mantis charset similar to the image below(I'm going to modify it anyway because I don't want to be too specific)

Any help is appreciated.
