Looking to add partner for part-time development on existing web service

Hi,

My partner and I run a RoR-based web service that we launched last year.
We've been getting great feedback from our customers, and are now
looking to expand the business greatly. We're interested in bringing on
a third partner, who would take on part-time development work in
exchange for a permanent share of the revenue generated by the product.

The requirements would be at least 10 hours per week contribution (with
1 month vacation), and good experience in Ruby on Rails. AJAX would also
be useful. If interested, please shoot me an e-mail for more
information.
