Looking For Good Used Parts For CNC

Hello,

Please bear with me as I am new to this. I am trying to put together
a 3'x10' cnc table for cutting foam. I need it to have an x y z axis.
I have the cad program and computers but nothing else. Any help with
sources of information, places to get good used parts. I live in
central Fl. Thanks in advance for any help. You can e-mail me at
mek0002@....

Thanks
Mike
