Total newbie here so i'm not sure if this is the right place for this thread, apologies if it is not. I did use the search function but couldn't find what i was looking for.

I recently bought a 40x60" router for wood working/cutting and a styrofoam plotter (i have worked with styrofoam for most of my life). I have a business running and i intend to branch out and produce pieces with these machines to sell in a decor/cotillion shop. Things like dollhouses, model furniture, airplane modelling, jigsaw puzzles, cake and party ornaments, etc. These are mostly made of wood but in my country it's very common to find them in painted styrofoam, i'm not sure if it's common in the US.

Anyways i am a businessman, not an artist. While i don intend to have lots of fun with these machines (i have hand built three computer cases so far) i need models that i can cut in the described lines of products. I imagine there are packages of models available in CAD for this sort of thing? maybe some free, some paid, like most things on then net? Can anyobody point me in the right direction?

Many Thanks in advance!
