Large Format Printing

Thought I might ask here, we are looking into getting into the large format/poster market/display etc. We are a large litho printer and have a number of customers who want to buy these items from us. I need to know the ideal machine (s) to start off with ie printer, laminator cutting etc. We are looking at solvent printers. Also RIPS and any useful software, we are geared up for litho at the moment. We are not looking at a big operation but enough to suit our needs.

Any pointers would be great

Thanks
