You say you can do this in a week, but you'll run into unexpected programming hurtles. You sound like you know your stuff but don't make the mistake of over-promising deadlines because this community will verbally tear you to shreds. Look no further than SJCX to see how coming up with new Proof of Work mechanism based of atypical things like storage and file sharing is really difficult. You have to come up with entirely new proof mechanisms from scratch and it's not as simple as it sounds. Your best bet would be try and network in the community and meet other programmers who have the time and willingness to take this project on with you because ICOs are not fair to the community (you could simply honestly hit brick walls in your abilities that you didn't foresee, even if you're honest). Don't bother releasing the coin before you're close to a working prototype unless you want to just make another shitcoin scam but frankly you'll only make a few thousand dollars these days pulling that crap. I'd give this project a couple months deadline if you know what you're doing and have a handful of guys working with you. Good luck.
