I just skimmed over your first system link,
To be honest if I were contracted to code just this system for you I can see in the first instance at least several hours of reading and comprehending (that exhausts your $75). This would be followed by numerous correspondences, that due to time constraints could takes a number of days and many further shadow hours.
At a reasonable hourly rate, we would already be approaching multiple hundreds of dollars in payment for my time committed, and that's before I have even set down the first line of code.
The coding itself could take days and days and days, and the bugs would be thick on the ground which would require more correspondence and more time and more coding, etc.
At this point we would be WELL over $400 and NOWHERE near a completed product for just your first system.
Now here's the rub. You say you paid $75 to Victor to have 3 systems coded! I suggest to you that Victor was well aware of everything I have written above before taking on the job, and so could never possibly deliver on the contract for said amount.
If you seriously wanted Vic to code these up for you then you should have at least added a zero on the end of your $75. But for whatever reason, forum history shows that Vic's long standing record for delivering on promises is abysmal, so you probably dodged a bullet there.
Victor should not have taken such a token amount for such a mammoth task, and you should not have offered such a pittance to possibly earn a king's ransom.
In summary, you both deserve this outcome and each other.
This is all just my educated opinion of course, and nothing personal intended.
Whether the forum soon closes or not is beyond me.
