I've worked for a few contractors who still strap on tools, but for the first time I've worked for a real builder.  They're a high end remodel company who has given me the chance to step in to replace their existing electrician (who has been fired).  Now I have completed their punch list.  Up till now I've done all of my work on an up front basis and this job has been done with no preconcieved price.  I live in NC and am not quite sure what to charge.   I plan on charging $65 for myself and $25 for my experienced helper whom I pay $13, and %15 on material.  I'm comfortable with this but I don't want to short change myself nor do I want to  discourage my client.  I know this is vague, but I really need some advice.
