Is that your monthly budget? Or what you want to spend in total on a machine. If monthly, there's all sorts of great options available from Xerox, Konica Minolta, Canon, and Ricoh. If that's what you want to spend in total, then printing is not the right business for you to get into. A good production quality digital press that will be able to print on gloss cardstock day after day will start in the $20-25,000+ range on the low end. And besides the printer, you will also need finishing equipment such as a cutter to cut down the postcards, a folder, and so on. If you buy a $700 desktop laser printer, it will get destroyed by the thick glossy card stock after only months of use, and the quality will not be up to the standard of what you're customers demand.
