I've upped my prices twice since I started 5 months ago.  They're in the top end for my area now and if anything I'm busier. Go for it!

I charge ?70 /15m and ?100 for ?30 and ? 140 or ?150 depending on area for 1
I'm quite highley priced for my areas but I normally hit my target 3 in day and 3 in evening unless it's a dead day.

I increased it from 120h and added the other rates later I find plenty people don't have a problem

  That is a really good rate.  Can I ask if you work in the South?  That is a high class escort price.  Hate to say this but being young and gorgeous would help.  Sorry if this comment might offend anyone.  Would I be wrong if someone is an average Jane and middle aged working in the North, it would be less than ?150 / hr but I could be so wrong.   

Yup, I might take a look to see..thank you, cherryfcuk.
I didn't want to say but I wouldn't consider offering 30 minutes for 50/60/70 ever.  I wasn't gonna say this but it might be worth thinking.

Clearly, you need to price up your 30 minutes to "compete" with local brothels who offer it for ?60.  That must be the underlying logic to offer such a "cheap" rate.  These guys are probably a little younger who might need a little more frequent "quickie" usually with a high volume escort use (ok, not passing any judgement here but I have known one who came to see me and still phones me got hundreds of AW feedback.) A punter told me that 30 minutes mean that they want "holes" whereas for a longer booking, they look for the companionship.   There's nothing wrong offering cheap services but as an indie, it's a bit like operating as a "parlor girl".whilst you are actually an indie, who can decide how much to charge. 

This operation works if you have a very discreet flat as it's bound to be "high-volume".  Since I need to be discreet, this approach does not help but will harm my civvie life.  I know how important money really is but I often think this setup will attract the undesirable attention from neighbours within a matter of days.  They aren't blind / deaf after all.  But if you have a discreet premises, choice is all yours, your body and your choice.
