Thats good, at least now I understand the problem and we shall start with the basics.
We have a power supply failure and we need to get that working before we worry about others.
Below are 2 links explaining how to use the test lamp and DVOM in details. In your case, getting the test lamp should be sufficient for now. They should be easily available at parts stores and would not cost much. Get one and you can start some DIY yourself.

Locate the fuse box under hood and note the location of the various components.
Connect clip of test lamp to body ground or the battery negative terminal. Point the test lamp probe to the positive to ensure test lamp comes on.
At either side of MAIN (80 A) fuse you would notice a bolt holding the fuse. Use the test lamp to probe the bolts on either side and if test lamp lights up, the fuse is good. If only one side of bolt lights up, the fuse is bad and has to be replaced.
If above is good, remove IGN fuse and put it aside. Unplug the ADD fuse and plug it into the IGN fuse slot. Turn ignition on and if dash lights comes on, the IGN fuse is bad and has to be replaced.
If you have a DVOM, you can test the fuse to check the resistance but without it, you can still use the test lamp to test the fuse.
There are two types of fuses, one is with 2 protruding ends whereas the other has 2 recess slots.
For the protruding type, hold one end of the terminals to the battery positive terminal and use the test lamp to probe the other end. If test lamp works the fuse is good.
For the recessed type, use a wire to plug into one of the slots and hold the wire to the battery positive terminalwhile probing the other slot.
Similarly, test all other fuses to ensure they are in working condition.
We start here and let me know the progress. For the guys who took your money, go get the money back. Pay to me, lol, just joking. These are the black sheeps of the automotive industry and from what you have described, I believe they are not qualified mechanics.
