This is the best "Looking for Tech CoFounder" I've seen in a while on HN! I've been commenting on the bad ones and giving them advice on how to word it correctly. Thanks to this post, I can just reply in the future with a link to this thread. ABSOLUTELY BRILLIANT!
I so wish I were in a position to help you - I would use this service in an instant and can tell that you will be wildly successful. Sadly, I have to work full-time to pay my bills and I'm a rails guy, not a django guy.
Someone is going to be very lucky to get involved with you. Please come back and let us know when you get that hockey stick curve - it WILL happen - I'm CERTAIN of that.
FYI - if you decide to expand your offering to Southern California, please let me know. My email is in my profile. My fiance can get the spa's signed up - this would be a dream job for her (not partner - just sales rep).
