Printing set up Suggestions

Hi

!!!NEED HELP!!

i am currently in the process of setting up my own inhouse printing for my design company.
i want the ability to print small run projects such asd business cards, leaftlets, flyers and even small posters.
im am quite willing to outsource larger pieces of work in the begining but would aim to take complete controil of that in the end.

essentially we need the ability to cut and fold which we can do manually to begin with and then we need some kind of fast but quality digital printer with dual side printing

any suggestions on which printer is best ????????????????????????
