I'd recommend me, but I'm admittedly biased.

As for printing, I agree that the source is usually not a problem. Since it is not a major business expense, I tend to favor a local printer who is well established. Not only are you supporting local business, you can pick out the stock by "touch and feel" and even get press proofs if needed (I usually recommend them). It's much easier to control the quality and schedule. Local printers are also more prone to put extra emphasis on customer service and your satisfaction. They usually have competent staff with experience which can make a big difference too.

I know you already bought your first batch of cards, but this might help for future reference and getting all the other materials you will need.
