As others have said, I would really consider whether punting is the most sensible activity at this point in time. In spite of the confident statements made by the government, I fear that we've still got a long way to go.
One thing I would draw your attention to is the following "All this services are extras so please use the number displayed on my profile..." The English is quite bad and I'm not entirely sure what she means, however it is safe to assume that the £150 is a baseline price for an extremely basic service (i.e. sex and covered oral). If you want a more "intimate" experience then I suspect you'll find yourself paying handsomely.
This is why I tend to avoid Brazilian girls. Maybe I've just had unfortunate experience in the past, but the advertised price tends to be significantly lower than the cost of a genuinely enjoyable experience. This is something to be aware of, at least.
