Welcome to bonsai! While growing them from such a young age is very fun and rewarding, it also takes 5 years or more. What I would do is pot them up, care for them, love them, and wait for them. In the meantime, go out and buy a tree and try to get the care right. It is different from other plant care.

The seedlings will not be ready for a long time to be bonsai, but they will be worth it. Like I said, buy one or two other trees, nothing too fancy to start, and focus on them while you wait.

Yeah, that was my plan.

Currently looking for indoor varieties since I'm not going to be living in a house for much longer *moving out after university* and I can't guarantee I'll have a balcony.

Just a bit concerned about finding a good specimen since there aren't any actual Bonsai nurseries around us and I don't exactly trust Wal-Mart lol.

I've read that ficus is a good indoor as well as Fukien Tea, but the Tea is very finicky...

I would recomend the Ficus, they are very cheep and easy to make a Bonsai with , plus they seem to grow pretty fast so you can see results within a few weeks (will it live, will it die, did I cut off to much of the roots,or did I trim it the wrong way) these questions will be awnsered alot quicker using Ficus for training and help you become more confident in your new learned Bonsai skills. Also buy a few Ficus try different soils experiment with new things find what works best for you and what style you like best , it will help later when buying other more expensive plants for bonsai, you will know what your looking for in a plant (root structure, branching , leaf size, and over all shape). Good luck and have fun , remember Bonsai is Living art and if it looks good to you that is all that matters, if others like it thats a bonus.
