I could dedicate 4-5 hours a day on working days (Mon-Fri) and 7-8 hours on weekends (Sat-Sun).Hours with flexibility to extend depending on urgency. I'm flexible to work on client system (through Citrix or any other means if required by client). Time Line and clear expectation should be discussed upfront in writing (email). I'll prefer to have a call to discuss expectations and time line during kick-off. Telephonic call (or skype calls) or mail communication would be preferred. I expect client to bear the cost of calls.
