Help son’s dream come true

Hi. My name is Alexander, I live in Russia in the small town of Nakhodka. I have a son, his name is Vlad, he is thirteen years old and he dreams of a personal computer. I have worked honestly all my life, but my salary is small, and the computer is very expensive. I love my son very much and I want him to grow up happy. I am not very friendly with the English language, so I used google, I hope you understand me. Thanks.
