As with GFE, PSE is an almost meaningless marketing acronym.
Whether anal is available, and if it is, whether or not you charge more for it, is entirely up to you.
If what you offer as 'PSE' is "bloody hard work", it sounds like you want to charge rather more for it than the other bookings.
No matter how much you charge, too many "bloody hard work" bookings usually leads to problems one way or another.
