I think the majority of Gabriela have friends who have friends and so on, not counting work colleagues, relatives and the rest of humanity.
Not just for me and You have been asked to help purchase, assemble, repair, install, recover and so on.
If the issue of purchase of computer and accessories is rather easy to solve (I have 2 of the store where my "friends" make a nice discount and pay a little more attention and care, and I make the offer even more, well, banal and trust), but the question is how to ask people for their work arises very often.
With one hand on the box, and on Habre slipped stories, where the Windows reinstallation asking 10 kilorubley. So people are paying!
On the other hand conscience (who you invented) does not allow you to borrow from your friends or colleagues.
To deny it does not always work.
And you, %username%, appreciate your help? Can anyone have a adequate price, or the method of calculation?
