[Metalab] Request for Soldering Assistance

My apologies for writing to you all in English, but my German isn't very good. I'm a student at the University of Vienna. I have a motherboard that needs three capacitors replaced. I have the replacement capacitors and it should be very simple but I have no experience with soldering and I'm afraid of ruining the board. Would anyone be willing to do the replacement for me, or at the very least guide me through the process? I offer my eternal gratitude and your choice of beer or coffee. Many thanks, Nate
