Ask HN: Can you sell a 'nearly' startup?

Before my current project took off and we raised venture funding, I was working on a side project which I almost took live but decided not to at the last minute due to time constraints.

It is a project local to the Swiss market, with a great working technical component, deals with suppliers and partners, marketing/graphic components already made and over $10k in 'promised' revenue (which I never charged as I didn't take the project live).

I rediscovered the project recently and it seems a shame that it is just lying there unused. Yet because there isn't yet anything similar available for Swiss consumers, I'm not willing to give it away for free as i have done with other side projects in the past.

For someone with German speaking skills and a bit of a flair for consumer marketing, as well as 3-4 hours/week, this would make a very lucrative side project (probably).

Anybody have experience in selling (or not selling) their side project?

I'm not looking for much more than a symbolic 'thank you', but I would like something in return ;)
