Unless you've got a badbwoy printer you're unlikely to have the print quality to compete with the pro disks in the shops.
So approach a printing company and check the cost of doing a short run - you'll probably have to order a minimum of 100 or so.
Then just use them as you need them.
Most printers will be well used to printing CD inserts so you shouldn't need to deal with a specialist company. Check the phone book and get some quotes.
If you're using a pro company to duplicate your CDs they may offer a printing service too but check around to see you've got the best deal.
