Finding people who know proper British spelling and are willing to work for cheap is easy - India was a British colony and the largest group of people doing O and A levels is there.

Oooh! Dangerous assumptions. The Indians have their own dialect(s) of English. As do the Antipodeans (at least two flavours); the Caribbeans (half a dozen or more); the Irish (North and South). And every other native English-speaking country and group.

Heck. Go anywhere north of the Watford Gap and if a girl talks about "being made-up", it's as likely that she is happy about something, as it is that she is wearing cosmetics. (And there are at least two other interpretations of that two word phrase: "made-up ground" and "bottle of made-up vodka & orange".bnc).

And if you start considering colloquialisms, you're into nearly as many regional variations within the British Isles as there are counties. And that's before you even begin to consider things like youth culture and so-called business-speak.

Once you go beyond 'Received Pronunciation', which not even the Queen speaks any more, there is no such thing a "Standard British English". Neither pronunciation, nor grammar. Even British Academics are having to to show flexibility in what is acceptable these days.
