Ten gallon batches aren't very realistic for someone who has never brewed before and who only has a "kit". Boils of that size on regular stoves are all but impossible (if not completely impossible) However, I'm all for jumping in head first. My philosophy is buy big at the beginning...buying small at the beginning and realizing you need "bigger" later sucks, and it is a waste of money. He needs a propane burner and an adequate sized brew kettle. You are looking in the range of $300 - $400 for those alone. Then you have chilling considerations, etc, etc, etc. If money is no object, hit me up and I'll hook you up. If money is tighter, stick with the pot cford1 posted. Good luck.
