You can stratify them in the refrigerator. Spread the seeds on a layer of damp paper towels or coffee filters. You can also layer the towels or filters to save room. Label each layer with a permanent marker. Fold them up loosely and stick inside of a baggie or open zip lock bag. Let them sit in the fridge for 3 weeks. Make sure the towels or filters don't dry out. After 3 weeks, surface sow on your seedling/germination mix and use a clear plastic dome over the pots until the seeds sprout. Because they're surface-sown, the seeds will need moisture surrounding them. The easy ones should germinate in about 10 days.
