The trick is the technique.
First, tools. You have to have a microscope or magnifier to see what you're doing, a pair of very good but not too sharp tweezers (I use size 00), and a smallish but not teeny-tiny soldering iron tip. Some smallish solder wick and fine solder (.020" ideal, .031" acceptable) are needed as well.
The first resistor may be removed by placing the soldering iron tip across both ends of the resistor at the same time, so that it is heated up at both ends. Then lift it up with the tweezers, or it comes up on the iron and you pull it off the iron with the tweezers.
Now, use the solder wick to remove the solder from the PC board pad that is on the left if you're right-handed, so that the end closest to the iron still has solder.
Do the same for the other part.
Now, with the correct resistor in the tweezers, hold it in place and heat up the solder blob while pressing the resistor into position. Then quickly solder the other end with the fine solder. Don't linger with the iron; the other end will heat up and the part may stick to the iron again.
Repeat as needed. "
-----------------------------------
This is tricky work! If you don't have a lot of soldering experience, you will probably mess it up...and you need good eyesight and steady hands, and a clean, well lit area to work in.
If there is any type of college or industrial place nearby that deals with small circuit boards they might be willing to help, if you ask nicely....

It looks like your parents did a great job raising you and your brother. You both are excellent examples to follow. Tell your Bro, Thanks from all of us here on CD!!
