I tried ordering from some of the Recently blogged about and even highlighted in a magazine calligraphy stamp makers, and still haven't heard back from them weeks later. This one From LoveToCreateStamps.com had a proof to me in less than 3 hours, and I had my stamp in hand 4 days later. Oh, and it was less than $25.
You could also have custom stamps made for paper projects like your escort cards, welcome bag tags, candy bar bags, etc.
