I feel like the grumpy old man but "in my day" we paid the SP her donation for the hour (usually $160 although I do recall $130 rates at LFMJ) and the only real consistent extra was Greek. If it was on her menu, it was included.
Now it seems like most agencies are $180 with the up sell (don't get me started on the agencies with the 160/180/200/220 pricing tiers)
Things I can recall of the top of my head that I have been offered:
Anal digits ($40)
BBJTC ($40 to 60)
BBJTCIM ($60 to 100)
COF ($40 to 60)
DATY ($50 - one SP)
Greek (anywhere from $40 to $100)
GS ($60)
MSOG (yes one SP said it would be another $60 to pop twice)
