Where to Order 100% Organic, GMO Free Vegetable Seeds

Options
Alright, I did a search and found a lot of conversations about GMOs, but not something that pertains to what I'm looking for. Most just seem to be pros and cons and a list of processed foods that contain them. My husband and I are going to be putting in a small greenhouse, so we can grow our own vegetables year round and be absoloutely certain that they are organic, and did not just have an organic label slapped on them (since that's not really controlled at the moment).

So, as the topic title suggests, any one know of a reputable place where one can get organic, non GMO seeds?
