decommission hybrid exchange server 2013 and finish office 365 to cloud move

I am looking for an experienced IT professional who can help me decommission my existing hybrid exchange server 2013 and complete the move to Office 365. My current hybrid exchange server is fully functional and I need to have it decommissioned within a month. Fortunately, I do not have any significant issues standing in the way of completing this transition. The right freelancer should have the experience and know how necessary to complete this project within the timeline established.
