If you're serious about having a comprehensive bike fit, then Bike Whisperer are fantastic. Couldn't be happier with my experience. They'll also give you incredibly detailed measurements to take away (as well as setting up your cleats/ shoes, etc.)- which means that any of the shops you mentioned will be able to advise on the perfect frame size.http://www.thebikewhisperer.co.uk/
One thing that Condor don't publicise well is that they are very happy to take on custom commisions. For example, on the Acciaio (lightweight steel), they only charge £150 extra for custom geometry and full custom paint. They'll also consider using different tubing, etc. if you really want to customise your frame. They're built by Deddaciai in Italy. Apologies if this sounds like an advert, but I've been looking at their frames and have done a bit of research for myself! I don't know if the same applies to their Ti frames- maybe worth checking with them.
If you want an off the peg Ti frame, what about somebody like Van Nicholas or Enigma? If you get a bike fit (which is a worthwhile investment irrespective of buying a new bike), then you can buy a frame with confidence, as you'll know your measurements.
