Ruby hacker needed for 1-2 week gig a short bike ride from Cambridge

We're a small, friendly startup ( http://SmartFlix.com ) and we need 1 week (plus or minus) of work by a good Ruby / Rails hacker to develop a feature for our new site ( http://HeavyInk.com).

If you want to get a toe wet in startup culture, this would be a good way!

All code can be released as open source, if that's a consideration for the right hacker.
