I have done a little cement rendering in the past, but not much. Can anyone
advise the best mix of sand, cement, and possibly lime and/or plasticiser
that will give best workability?

1:1:6 (lime, cement, sand, by volume)

How much I will need, for 30 sq mtrs?

You can calculate the volume. Density is around 2.2.
