We are looking for these things:
1) multisig 2/2 wallet.
2) user wallet - online - that functions like blockchain,info (which is, user operates the wallet locally in browser, the site has no access, but only holds the users encrypted data).
3) programed 2/3 multisig setup (for large trade contracts).
Security is a must and would like secure remote control on another site in case of ddos attacks. If you can't do all of that give me a quote on what you can do. Must have prior experience with IT security and bitcoin systems
