Gritty, urban, hand drawn logo for creative arts project

Information for the business: Creative arts project
Design details: Gritty, urban, London, miserable, witty, real
Theme: launderettes
I need a logo I can use across media, plus other design elements (including font etc)
Target audience: Hip, politically engaged, arty, Guardian readers, poetry
Ideas for the visual style: NON-CORPORATE, line drawing, by hand, impact, shock, urban
Things to avoid: Nothing shiny, nothing polished, nothing commercial, must be one-off and hand drawn
Preferred colors: monochrome, possibly including yellow
Where the design will be used: blog, twitter, Facebook, business cards, flyers, stationery
Extra notes: I don't want anything that looks mass produced or corporate in any way.
This is for a project about people's real lives. It's an arts project with hard-hitting political impact. I'm not trying to make money, I'm trying to make an impact and engage people, get them to listen.
