Ask HN: where to find someone to maintain a Ruby on Rails project?

OK, I've got a site that I built a couple of years ago for a client; it's in good shape and is stable and very low maintenance. The client now wants some modifications to the site, and I've moved on in my life and am no longer interested in consulting.

The site is an order-taking system for a small business that sells pre-assembled ready-to-cook meals. Customers select from a menu of options, choose a pick up date, and then pay with their credit card. On the back end, the store's owner looks at a summary of each session, prints meal tickets, and schedules pick up times and menu items for the next month.

The site is at:

The code is about 4000 lines; 1500 lines of app and 2500 of tests (in the test-driven style). I built it just when the Agile Web Dev 2.0 book came out, and it runs on Rails 1.2, not 2.x.

So, there're a bunch of job boards to choose from: 37 signals, Working on Rails, Ruby Now; what have you people had luck with? I want maximum return for minimum investment of time. Of course, the benefit of posting this on Hacker News is that there may indeed be a hacker interested in this project.
