Sources of good, tailored trousers

[R.O. Thornhill]

Here's my situation:
- I get most, if not quite all, of my clothing bespoke; and am pretty pleased with the value equation that bespoke represents
- When it comes to trousers, however, the typical Savile Row price tag (+£700) has so far put me off buying bespoke odd trousers
- Instead, I buy trousers from a variety of RTW makers, but the fit is never quite right and I feel limited by the styles and fabrics offered

So, I am after any recommendations for sources for 'cheap' tailored trousers (perfectly happy to pay £300 or thereabouts for basic cords, twills, chinos; and a bit more for flannels). Can be either online (but how reliable are these onlines tailors when it comes to following measurements) or from a London-based tailor.

Any ideas?

Cordings for corduroy trousers. They're excellent.
