The problem is, nobody is going to trust you with their hard earned cash (coin) without publicly available information - and that ultimately is where this project will die.
To even give me an incentive, you need to:
1) Invest in your "project" - hire a web developer, create a secure storage network and prove it's secure.
2) Publicly display your contact information - create a company, list who you are, where you are based, your background.
3) Show proof that 5-years from now, you won't be arrested for illegally operating as an international bank.
4) Your policies - how are you going to deal with money laundering? Criminals will store bitcoins in your "bank" - what is your approach to targeting these criminals and reporting them to law enforcement? (It's your duty).
The list could go on, and on, and on.
