I'd look into ready mix screed m8,I've just laid 36m2 @ 100mm on a similar job. I told the batching plant what it was for and they sorted the strength out-it had loads of fibres in it which help the screed maintain its strength. Compared with how much it cost against how long it would take to mix-well worth it
Mixing by hand can be a pain as I've noticed from past jobs its either too wet/dry,sticks in the mixer etc etc etc

Thanks for your reply will look in to it, can you remember how much it cost for your 36 m2
