Starting a patch from scratch

Ok - I've finished the raspberry patch and I will do this! 

I need advice

It needs to be as low maintenance as possible - I have the garden to look after but I really want to do this.

The area is 30ft x14ft - grassed. There are trees nearby so it does have roots underground - but no other options. 

How would you tackle this. 
I would like to go no dig? I ave weed membrane - and more wood chips than you can imagine. A small amount of compost, manure and lots of card

Can I just cover with card and go for it ....
