Changing Fuel Injectors for 1st time, need some guidance

I need to change the fuel injectors on a Volvo S60 T5. Videos from the Youtube make it seem like a pretty easy job but I still have a little fear since I have owned the car for 3 weeks and found a bunch of hooptie repairs that were done. I have a concern that my inexperience might make things worse instead of fixing the bad injector.

I am willing to buy the end all of nice dinners to someone willing to step me through changing the injectors. I have step by step directions (with pics and videos) showing the process, just need an experienced idiot checker.

Any takers?
