dating site

I have a probably new idea for the workings of an online dating website, compared to other sites the implimentation should be fairly simple although it requires such elements as logging in of users to track preferences and among other differences it is centered around an instant messaging approach instead of an inbox messeging aproach. I also have some webspace although right now it is unlikely to support the load required. I'm looking for someone to work with me on the idea. It could be a paid project depending on your level of involvement and this is verry much open to discussion.
