But I will never have a LP with metal stem. I have to rely on Annual Pillars with Xin/Geng stems then?
What I mean is that you were in Metal LPs but Metal was weak, still it helped. Your chart does not like Metal in Branches so there is no such year which would help to control Jia and not to produce Zi at the same time. Producing or helping Zi is bad - you will loose a lot of money.
Fire in stems also good.
How bad for me is it going to be this 7K Jia/Xu LP? 
I'm interested in my health and wealth.
Guan Sha or 7K Jia is not that bad in the chart as it combines with 2 Ji. Otherwise you would not be your own boss. Jia here is actually money not power.
Problem with marriage is because the Marriage Palace is involved in Punishment and your men belong to other women.
Jia Xu LP will not be bad:
1) Jia is arrival of Jia from the chart which is your money. Jia overcomes DM but as I said before there are 2 strong Ji it combines with. It is not control but Jia becomes auspicious. I would be aware of competitors.
2) Xu is arrival of Xu from the chart. Xu-Wei punishment will be in action but you have very strong body and Xu-Wei is punishment within the same group so health should be ok.
Xu will entomb Seal Si, it is another work - good too.
Gui You LP is not good:
1) it produces 7K Jia.
2) You harms your root in Xu and marriage palace at the same time.
3) chart wants to control Zi but You produces Zi. It is very inauspisiuous.
Forgot to add:
4) Gui is arrival of Wei-Zi harm.
First I almost died when giving a birth, doctors barely saved my life.
2011 is Xin Mao LP Gui You.
Mao moved You to harm Xu which is your body.
I went for bankruptcy, had to let go all of my employees, and close the store.
You produces Zi - you loose money. Shen, You, Hai are not auspicious for your chart.
You harms Xu, Xu can not control Zi any more.
Another proof that Jia Zi is the correct hour: 2009 Ji Chou you moved in with a guy - Jia+Ji, Chou+Zi. Spouse Star is active and he did have relationship with somebody else because Ji is Jie Cai combining with Jia.
2014 Jia Wu you moved out - Spouse Star Jia Zi is clashed by Jia Wu. He is gone!
I attached your chart so others could participate and correct me if needed.
