Self-managed 401k advice

Hi everyone,
This is my first post on this site, but i am a long time reader and donator. (been reading since ~2010)

a bit of background:
debt free except mortgage
~3 months living expenses, (6 months surviving expenses )
holder of physical silver and gold (and ammo)
401k worth ~14k that has recently been moved into an account that i can "self manage"
dont know much about trading other that the market is rigged.
expect to have my current job for no more than 10 more years

my goal is to grow my 401k which can be pulled out when i lose my job or before hand if shit starts to get a lot worse.

i am interested in investing in energy, metals and similar "hard assets'. I am interested in the sprott funds and things similar to it.
I have a few sample portfolios that i have been given, it has some suggestions from a like minded guy but i am not really sure where to start.

I am not sure how often i can buy and sell, but if possible i would like to keep it to a few times a month...again not really sure if that is possible, but i know i cant day trade.

I will leave it here for now, as im sure i have left some needed in out, but will respond accordingly.
Any advice that you can pass along would be greatly appreciated

thanks in advance.
