Frankly I would not take the chance, £80 h/h and £120 for the hour is a lot of money to gamble when there is already cause for doubt, but your money, your punt!
Probably like me you're after the new and exciting rather than sticking to the regular girls you know will do a good job, if that's the case can't say I blame you
Let us know how you get on if you do decide to dive in?
