My preference (when I was consulting) was to offer the services of an "observer"
Let them prep, let them assemble, let them tack the assemblies, let them weld them out, LET THEM REMOVE THE BACKING BARS, let them cut the straps, and let them perform the bends... All under my watchful eye.
Charge by the hour.
This way, the QA/QC department and production leads are typically forced to be involved. This involvement makes them better at their jobs, and makes it much easier the next time I visit.
But if they are going to have you do more of the physical part, calculate what that time will be worth to you and charge per welder....
It's fine to do it either way really, as long as YOU are satisfied when the job is done.
My experience is usually that the first time around; The WPS's are garbage, the processes are out of control and most of the welders fail the test the first time through......... Then you have an option to offer your customer.... They can take two more plates for every 1 plate they fail and most likely blow it again at great cost and time, or they can receive some of my Special High Intensity Training (S.H.I.T) and actually become better at their jobs and comply with the code at the same time :)
It's a racket that American manufacturing needs more of :)

We normally charge per test coupon for each certification. But there is a minimum charge per day.
Example: minimum charge is $1000 per visit...$200 per test coupon regardless of pass or fail result.
If one welder was qualified in one day for one test coupon, the min charge applies i.e. $1000
If six welders was qualified in one day for 6 test coupons, the charge is $200 x 6 = $1200
