Migrate co-op pages from old site

I ran `ruby migrate_coop_pages.rb` in `scripts`. There will need to be
some manual tidying up of the generated `.md` files under `_coops` but
I think this is a good start. As a one-off it doesn't warrant the time
it would take to improve the migration script.

+We’re your technical co-founder.

+
+Come and talk through your idea with us. We listen, and help define the core problem to be solved. We propose a workplan for a fixed cost 5 day sprint. At the end of the sprint you have something live, to visit or download to your phone; something to test and put in front of your users. Based on your feedback, we work together to define the most important thing for the next workplan.
+Plan. Build. Review. By repeating this simple pattern we can take you from idea to new business in a matter of weeks.
