Dear Anna,
Your problem is not lacking of noble. Your problem is very caused by obstructions of your office. Based on your BaZi chart, I suspect that there could be some disturbance or changes in the SE / NW areas of your premises. Your problem should be in these two areas. Check and with your FS knowledge, try to fix it. You should be able to see better quality people coming in for jobs.
Also - in your BaZi chart, it does show that you have a HO seeing DO and 7K formation. This means, you may need check your people management skills too. It would seem that you are not winning people's hearts easily. Work on this skill and you will find that people matters improve too.
Cheers,
JY
