Company to print full color header cards for retail locations?

I am searching for a company that can print header cards that are used to hang products on peg board in a store. Something full color, 3x5", glossy, peg hole, and possibly on a roll so that I could load it onto a printer in the office to add the product details such as sku and barcode. I would think this would be all over the internet for companies offering this service but I can't find a darn thing, only 1 or 2 places.

What printer would you suggest to print the details in house on them? I am a small business with about 200 products but trying to make this as effecient as possible. Any suggestions would be great, possibly even a small business forum where people discuss these things.
