Ask HN: How to sell a foreign software business?

A friend of mine owns a software company in Spain with a small group (6-8) of talented developers. They have a nearly finished corporate security product that would compete with Box and similar. However, they are running out of money and their loan might not be extended. Since they've been working on product development and not sales, they have little revenue. At this point, they might be interested in selling the company to the right buyer, but they don't know how to go about it, and they asked me for advice. So I turn to HN. What would you do in their situation?
