Well, this is the way I would do it.
Putting the 6 switch disconnect rule aside,
I would run 10/3 on a two pole 30a breaker to a small breaker panel with only two 15a breakers I would have a means of disconnect at both sides.
If you need more than that it will start to get very expensive.
Use direct burial AND sch-80 PVC at 18" below ground.
But thats just me.
