would you mind making a list of what you can do, and what you need help for?
asking for "assistants" before naming all specific tasks needed/already covered and before giving details of your project's state won't bring in many people.
by project state I mean the progress in the diverse areas planned (levels, models, music, ASM, etc).
I agree you should remove the project deadline, as it means more pressure for people joining if you rush the completion. one year is rarely enough even for the most simple ROMhacks.
