I emailed her using all my energy and this is what she said.
"my reading prices are: £40 for 30mins, £25 for 20mins, £20 for 15mins, £15 for 10mins, £10 for 5mins or £55 for a longer reading lasting around 45mins."
as of today 1/4/20 those rates in US dollars are
$52.35 for 30mins,
$32.72 for 20mins,
$26.17 for 15mins,
$19.63 for 10mins,
$13.09 for 5mins or
$71.98 for a longer reading lasting around 45mins.
It's fairly reasonable.
