I work 6 days a week, 10 hours a day. My work hours are flexible and I can adjust my hours to whichever timezone you are in.
For example if you are in the US, whichever zone you are in the US, I can work your hours, or wherever else the the world you are.
During the work hours, I will exclusively work for you and I will be available on email, Skype, phone or webchat. I usually use Google Docs for collaboration along with Dropbox to transfer files, but I am open to using any collaborating platform your team uses.
