How to fix a lens that is won't open?

Anytime I turn my camera on it comes up with "system error zoom". It was working perfectly fine then the zoom started acting a little shaky when it was coming out... not being able to focus or zoom long distances or macro shots, then it just stopped opening. I am afraid to take it to a camera repair shop as they usually cost tons of money of which I don't have..... Any help with this would be greatly appreciate. Thank you :)
