Ask HN: Built a startup, took a real job, now seeing lots of interest. Now what?

A couple of years ago I built a startup (see previous posts from me.) As, essentially, a one man shop, I saw moderate success and even got to meet one-on-one with Mike Moritz then Bryan Schrier (tho, Sequoia turned me down for funding, but a great experience!).

Then I got a job offer from a bank (the vampire squid variety), I looked at my new wife and our mortgage and made the rational decision. Fast forward a couple of years and I'm seeing a big uptick in interest for my startup. I've kept the site up and am getting several emails daily seeking pricing info and vendor partnership interest. But, I have a job and no time to dedicate in pursuing these opportunities. So, now what?

Probably the best option here is to find a home for my startup. I would let it go for next to nothing to a qualified buyer willing to dedicate the resources it deserves. But how to find such a buyer? The service is a niche medical SAAS that requires some knowledge of the industry, and sites like flippa aren't great avenues for finding niche buyers.

Any other options you see here?

FWIW, have pitched to a few vendors. Direction that goes is: "I want someone else to do this, so I don't have to."
