Ask HN: How do I find a software best practices mentor / coach?

I'm trying to find someone who can coach/mentor an inexperienced software development manager in software engineering best practices--source control, release engineering, security, backups, planning, development methodologies, code review, architecture, etc.

The manager was promoted from within, the most senior developer from a group of relatively inexperienced PHP programmers. Unsurprisingly, they don't follow any formalized practices and are struggling with a lot of chaos and poor software quality.

The company is based in the Netherlands (Noord Holland), and doesn't have the budget to hire an experienced, full-time engineering manager, and this kind of coaching is outside the scope of the services I normally provide, so I'm trying to find them a local consultant who can do some phone coaching and come in a few days a month to help with training and process development.

Anyone know such a consultant in NL, or have an idea how to go about searching for one?
