If you're an apprentice, ask your journeyman. Or is this one of those "I'm doing a side job..." threads?

Run two 8 hots a 6 neutral and a 10 ground in pvc conduit. The breaker size on the sub panel does not matter as long as it is greater than 50A. You don't need a main breaker panel at all as long as there are less than 6 branch circuits and feeders from the sub panel. It does need a ground rod and main bonding jumper.

I have never been caught on it but if you check you will see that most ML panels will not be compliant if you don't use a main breaker kit. In most cases I use the kit not 6 discos especially now that I know it is not compliant. 225.36 is the art. and the instructions in the panel say that the ML panel is listed for service equipment when a main breaker kit is installed.

The 2014 does away with this except when we use an existing feeder that does not have an equipment grounding conductor.
