IMHO, as an electrician living in the condo complex, you probably have a couple of political problems that you will have to address.
1) You might be seen as having a conflict of interest, pointing out 'problems' to drum up business for yourself. After all, these things that you've been pointing out 'have been working fine for years'.
2) If you do convince people that there is a problem, you might be expected to volunteer to fix them at cost.
3) Some of the problems that you point out are not immediate safety hazards, but poor workmanship that will _potentially_ lead to early failures and safety hazards.
The shallow buried sch 40 conduit, for example: as long as the conduit is not broken, then the install is safe...but by not being deep enough and not being thick enough, it will be prone to breaking. These are also the problems that will be most expensive to fix.
The list of things that you find will need to be prioritized, and in some cases probably won't get fixed. Does the NEC apply in your area? You might not have the legal backing to get the poor workmanship fixed.
Good luck! I certainly would not want to live there, and you might point out to the condo association that these clearly identifiable safety hazards suggest poor property maintenance and probably depress property values.
