Hi Zion 2,
Actually, you're in luck. The USB port is contained on a small separate circuit board that also holds the power button, so no soldering is required to replace the port. HP even supplies the service manual showing exactly how to replace the part, and from my reading of it, it's fairly simple and straight-forward.
Basically, you just have to remove the bottom cover, unplug the battery, take out the hard drive and then the board is just held in with two screws. If you can work a screwdriver then you've got this! Here's the guide; the power button/USB port board replacement instructions start on page 44.

The specific part you need is apparently dependent on the color of your case; I assume the power button matches. Here are the three part numbers that fit. Note that you can use any color; it's just that the power button's color may no longer match your case unless you can figure out how to swap the old plastic with the new one on the button.

Here's an example of one I found for sale; if you do an internet search on your particular part number, I'm sure you can find more; they're available on eBay and Amazon and other places. If you aren't picky about the button color, just buy the cheapest one; they're all HP parts so you don't have to worry about aftermarket part quality.
