it's probably all relative to your past experience...
if your ppc isn't very good, likely that it can be improved enough to cover the premium and more.
but in general, i don't think they have the expertise that many professional ppc managers have - no proof of that, just my assumption that someone who specializes in particular in an area, will have a leg up on someone who doesn't.
ask them for a pay for performance arrangement.
