Practical advice for Micros in growth?

The Australian government has a most useful site aimed at micro businesses (defined as “businesses who employ 0-5 people”) in the start up – and exiting – stages.

Lots of helpful advice – but what is lacking is help for those Micros who wish to remain free agents, maybe as a mini network of competing colleagues ( I am really looking forward to someone finding the right English word for this Danish term!) while retaining their independence.
Does any member of MikroNet know of a source of information that deals with this topic?
