Grow your own bonsai: Starting from Seed

Purpose:
Growing bonsai from seed is a really great way to obtain a large amount of young growing material on the cheap. Growing bonsai material is not always feasible for a number of reasons. Perhaps the seeds are too difficult to grow or in the case of ficus, it may be better to obtain material from cuttings. This quick write up is dealing with growing bonsai seeds from seeds in general
Target Audience:
Beginner to advanced bonsai enthusiast or anyone with an interest in growing bonsai trees from seed. A basic understanding of agriculture is required.
Outline of instruction.
Have you ever grown fruits, vegies, or flowers from seed? You can follow the basic process for sprouting vegetable seeds to grow your own bonsai tree material.
The following is a short list of trees I have successfully started from seeds:
Trident maple
Apple
Citrus
Black pine
Pomegranite
Adenium obessum
I later found out that the listed trees don't always do well in Phoenix, AZ. The extreme conditions here just proved too much for these trees. Most other parts of the country however, should be just fine.
Growing seeds successfully does require some planning. First, you need to obtain the seed source. Next you need to stratify your seeds (if needed). You'll need to plant more seeds than you plan to end up with. And finally, you'll need to transfer them to growing pots
Obtaining Seeds
Some seeds can be collected from the  tree or from fruit you plan to grow. I'm currently collecting apple seeds from the apples I eat. If you cannot find seeds from trees or fruit, you can purchase your seeds online. Most home improvement centers do carry seeds, but these will be fruits and veggies or flowers. I've always purchased my seeds from Angelgrove Tree Seed Company <http://trees-seeds.com/>
Stratifying
In the wild, temperate tree are time to grow in the spring, and will not grow until a duration of exposed cold before they will grow. Stratification is a process where seeds are kept in cold storage to encourage growth. Stratification takes 6-8 weeks more or less. The purpose here is not to provide detail on this process, but to advise of this possible time-consuming step.
More is More
If you've ever tried to grow anything from seed, this one goes without saying, but I'll say it just the same: Be sure to plant more than you plan to use. Shit happens. You get a sudden influx of bugs, your automated watering system breaks, the neighbor's cat decides to flop down on your seedlings. You get the idea. Weed out the weaker ones later if you end up with a bonanza of trees, or sell/trade them out. Don't know anyone? Join a club, run a Craig's List ad, or just EXPERIMENT with your extras. 
Transfer to growing pots
Mostly seeds are started either in a seed tray or in small pots. Refer to my last point for reason: more is more. The more seeds you plant, the better your chances of successfully growing your bonsai tree. You can easily start 300 seeds in a single seed tray, where as if you used 6 inch pots for each seed, you'd run out of space.
