Pricing it too cheaply would I assume generate I don't want to say the 'wrong' type of clientele but I wouldn't want a load of mates (stay donor the like) who've thrown in 20 quid to then take the proverbial and also I think £50 for 30 mins or maybe 45 is pretty reasonable
I'm not convinced that lowering prices attracts the "wrong" sort (even though that's not quite what your saying). I think it can be rationalised in many ways, including the opposite, e.g. people who pay more will expect and even demand more for their money (although I don't think that's particularly true either). I don't know what your experience is when you've had lower rates (if that's ever been the case) but from my admittedly very limited conversations with a range of WGs who've been at a variety of price points - they all seem to report similar levels of issues or at least any variation doesn't seem to be due their rates.
I have heard that lower prices can lead to more timewasters but I really don't see how that's the case since timewasters have no/little intention of paying anyway! If it were me (and I'd booked but I was on the fence about actually going) a higher price would probably make it more likely that I'd cancel (or just not turn up - not that I'd ever do that).
I'd imagine you are correct about the increased "risk" with a bunch of mates potentially taking the piss but I think that's more of an issue with attracting a bunch of mates rather than the price and I don't particularly see how they're related.
I think a lower rate or £50 for 45 mins seems more reasonable. The reason I said it sounds expensive is because there are a number of good girls out there who will offer 1 on 1 full sex and at least OWO for £60. There are also two pairs of independent girls I know who do threesomes (FFM) for only £80 for 30 mins (one pair include CIM and both include facials). At Sheridan's (a parlour in Salford) you get 2 girls (FFM) at only £65 for 30 mins and this includes OWO and CIM (if CIM is offered - although apparently now CIM is often a tenner extra). Don't assume the girls are crap either because most of them really are good.
A more direct example is Saskia (who's very good both in terms of looks and service) at La Maison in Bury who recently charged £120 for a 2 hour greedy girl party. So it included full sex but it was apparently £10 extra for facials and £20 for CIM (although they were unlimited). The ratio though was 10 guys to the one girl.
Having said all that, I believe you're based in Liverpool so things are probably a bit different, nonetheless many Liverpool based punters often travel to Manchester for reasons of quantity, quality and price - so don't underestimate how relatively direct the "competition" from Manchester is.
Bloody hell, this post is far too long. As penance I'll post an overdue review momentarily.
