Build database of Ruby programmers

We would like to use [login to view URL] to hire some freelance Ruby developers. However, the site is virtually impossible to navigate. What I would like to do is place all of the data (21,000 developers) into a database by: - Name - Link to profile - Country - Available for hire (yes or no) - Number of people who recommend this person - Number of people this person recommends - Authority - Popularity - Forum posting rating I would like this database updated daily. Following that, I would like an interface where I can filter developers by any of the above criteria. You can find a list of people at: [login to view URL] I imagine one would have to build a crawler to start at "A" and work your way through, but you may be able to think of something more clever.
