On black printing,it's really variable data what you are printing? what is the run lengths of your jobs? You should consider a Digital Duplicator like Duplo.
I would recommend for this to start up with INTEC solutions. There are 3 options on digital presses and you could print heavy stock. Also they have finishing equipment. Send a mail to Michael. michael.sparbeck@intecprinters.com
