Sorry Buddy, I think your request is a tall order for an escort, 80e wont get you much unless someone is holding a spring sale.
Alternatives include a street girl (baggot street, grand canal area) for approx 60e, althought choice is very limited, only about a half dozen girls on the best of nights, or massage with a Chinese Girl (approx 40-50e) who might fancy a nixer (BJ?- not with many for 30 or 40e, HJ should be no problem,) check the massage ads in Herald, there about 20 to choose from.
Not much help there I know, but as I started- 80e is pushing it a bit, limits your options big time. Regards.
