From experience I would charge him because there is ALWAYS something unexpected that comes up which costs more than you anticipated. If you are fortunate enough to get the job and make far more than you would expect, return some $$ back to the guy when the job is done. That always is a good way to keep the customer extremely happy and ease your conscience. I do the same when I eBay an item and my shipping costs are far less than listed...I usally refund a little back through PayPal and it shows well in my rating comments.
