I do not have 8,000 coins yet. How do I attract the attention of other coin holders to bake their coins for them? How do I apply to become a baker once I have the required 8,000 coins?
In regards to the first question, on how to attract the attention of other coin holders, I think it is simpler to instead delegate your coins to a baker. There are many such services, you can find a list here.
For the second question, that is, how to apply to become a baker once you've acquired a roll. For this, see the tezos documentation here. It amounts to running a command with tezos-client, that registers your key as a delegate and then running the baker and endorser daemons.
Feel free to delegate to Tezos-Japan
When smart-contracts are available that allow for baking bond contracts then we can work together.
