Maybe consider.....
Im new to PERB and MP's in general.. Hope this message does'nt offend..
I would suggest you maybe try to find a regular SP to be with and then enquire about a discount? I've been going through most of Trawlers favorites

(Thanks btw!) and one girl whom i had great chemistry with offered me a substantially lower price then I expected, and told me repeat visits would be that rate... Dont bother asking me who, its private..
I would think that being an SP could be pretty tough.. and im guessing most SP's would rather see 'regulars' that they liked rather then total strangers all the time.. Would be interesting to get some SP's opinions on this topic..
Just a thought, maybe a different strategy...
