Thanks for the intel, chaps. I'll keep an eye on her rates and location, and if both align for me, I will give her a go.
Her prices fluctuate somewhat. I've seen her profile showing half-hour rate as £60, £70 and £80, and hour rate at £100, £110, £120 and even £130.
It seemed she had settled on the standard £60/£100 but half-hour rate is now £80 and that's too much for me to TOFTT, particularly if she was hesitant over FK.
