The following list has a lot of certified organic seed companies as well other companies who sell heirloom and wonderful varieties. None of the companies below sell Genetically Modified (GMO) seeds - they have taken the "Safe Seed Pledge."
I love these people - I've been getting Jere Gettle's catalog since I think he was still in school, and he sure has turned his passion into an amazing company! The catalog is absolutely gorgeous - the photos make it clear that these people sincerely and truly love vegetables and plants! And the variety of totally cool things! Just awesome!
Unfortunately it seems that Bountiful Gardens has closed it doors for now - This was John Jeavons' company. He is the pioneer of Bio Intensive Agriculture, and has written How to Grow More Vegetables and Fruits (and Fruits, Nuts, Berries, Grains, and Other Crops) Than You Ever Thought Possible on Less Land Than You Can Imagine and The Sustainable Vegetable Garden: A Backyard Guide to Healthy Soil and Higher Yields, two of my favorite gardening books. I practice Bio Intensive Methods on my farm and have based much of my own gardening-philosophy upon his books. The seeds he sells are chosen and developed to work well in intensive, organic, sustainable systems.
Seed-Sourcing - some of my favorite places to get great seeds:

First, a quick explanation of seed labeling....
Certified Organic Seeds
Certified Organic are seeds that have been harvested from certified organic crops. These seeds may be a hybrid or heirloom variety, but they cannot be treated with any chemicals. And certified organic seed cannot be Genetically Modified (GMO).
Heirlooms are seeds from cultivars or varieties that were grown and used during earlier times. Basically, they are seeds that were pushed aside for modern, large-sized, factory-style agriculture methods. Heirloom seeds have been carefully saved and stored and preserved over many years by people who appreciated their unique characteristics. Many heirloom seed varieties have retained their traits through open pollination.
Open Pollinated Seed
Open pollination is pollination by natural forces like wind, insects, birds, etc. Open pollination is nature at work adapting and changing and diversifying. Open-pollinated plants will produce seeds for new generations; however, because the pollen of these plants is uncontrolled, open pollination may result in plants wide genetic variations. This increases biodiversity, although if you are not careful you may lose the characteristic you love about a certain heirloom. You can do careful breedings of open pollinated heirlooms using row cover to insure that your heirlooms stay true.
Some people are breeding their own varieties using open pollinated seeds. These varieties can't quite yet be considered Heirloom, because they don't have the long history associated with heirlooms, but they are wondeful!
A hybrid seed is a naturally-bred seed, although it is not open pollinated. If a seed is labeled as a hybrid, that doesn't mean that the seed is bad or factory ag or GMO. Hybrids are bred to improve the characteristics of the plants, creating varieties with more yield, uniformity, disease resistance, fun colors, and so forth. Hybrids are produced by manually cross-pollinating plants. Hybrid seed cannot be saved, as the seed from the first generation of hybrid plants does not reliably produce true copies. The parent plants of hybrid seeds were bred naturally - they were not genetically manipulated as GMO's are.
