we dont have a store that sells bonsai in my area, but i will have a look as
a full tree would be nice.

I'm afraid you misunderstood Jim a little. He did not advise you to buy a Ficus
bonsai. What you should do is go to a regular garden centre, buy a Ficus tree
sold as a houseplant, and learn how to TURN IT into a bonsai.
Unless your pine tree seedling is dying, I suggest you don't try to repot it.
Let it alone & just water very carefully.
