Is the area well compacted or likely to settle?
I did a similar job years ago as you describe (except 50mm sand/cement dry
mix well stamped down).
But mine was on well compacted ground with significant clay content.
Check out www.pavingexpert.com for qualified advice.

I looked at this article and found it interesting.
I'm hoping to lay a small patio in part of a garden,
and am not quite sure if I ought to get a professional to lay it.
The soil is very soft in this garden.
I see that the diagram at the end of the above article
shows the slabs laid on a "prepared sub-grade"
covered with a 2in grit/concrete mix.

But what exactly is the "prepared sub-grade"?
