Dear [company] team,
I am currently organizing a Node.js beginners event on September 15. With 20 Node mentors, we are going to help about 80 attendees to learn programming with Node through a set of self-paced challenges. It's a nice proven concept and has already been held in several cities around the world.
We are still looking for sponsors to cover some of the costs. For 200€ you could sponsor drinks for all the attendees and also for 200€ sponsor stickers, which are intended to be badges for accomplished challenges.
We will promote your logo on the event page and the ticket page as well as during the event. We are also happy if some of you employees help out as mentors or even join as learners.
Best, [me] http://nodeschool.io/
