Well, yes, i know that, but actually getting the work is not quite as
easy as people think. I've had a reasonable past 2 months, as I'm
starting to get repeat customers, but it is difficult getting work at
all times, and if I started asking for £200 a day, then I'd get no
work.

Whereabouts are you? Around here (London E5) the going rate would be
much higher; and the quality of your English would allow you to command
a premium from a minority of the residents. And that's before even
thinking about going over the borders into Islington, the City etc.

Indeed, looking ahead to when/if I get the spare bedroom sorted, what'd
be your daily rate for London (with free bed/meals/beer/wine/jasmine
tea/whatever included) to help do a bathroom, garden shed, dry lining,
kitchen, ...................?
