Help me change someone’s life!

I'm a regular brazilian guy who wants to change the life of someone I have a deep care for, this person has had a tough time with life since I've known her. It may sound superficial, maybe, but I just want enough money to buy a computer for this person as a gift and this is enough to give her the opportunity that she wants for her work (the pc in the picture is just a mere ilustration, the computer will be used for work). My country is in a bad economical state right now and everything is too expensive for me to be able to get it alone. So I really believe that there will be people out there who are willing to help, and I will be thankful for the rest of my life. I apologize for not being able to offer any rewards, but I promise that every cent will count to realize her dream. I know i'ts not as important as a medical condition or bill, but I'ts also a lot less expansive and, as I've said before, will change her life.
