I charge $20 per hour but am always easy to work out specific time lines and budgets for those who require strict deadlines or some other financial arrangement.
I require 50% up front for new clients and charge for revisions AFTER rough artwork has been approved. *Rough art/designs are covered within the 50% up front (no more than 10). Usually, 3 roughs are done AFTER a conversation between both parties before any roughs are presented. This insures that everyone is on the same page and my system has proven to work best with the best results within the shortest time frame of completion.
