How can I replace the SD card reader? (Memory card error)

My camera was taking great pictures & I had just uploaded my photos & replaced the card in the camera when I had a message on my screen saying "Memory card error". I have tried other cards, looking to see if the metal/gold colored wire is in place to connect with the card, etc....I have also used canned air to blow-out any dust, dirt, sand, etc....from the card slot. Nothing has worked...Other ideas other than replacing the card reader slot ??

I LIKE the photos I got from this camera & would like to try & repair it ! Please help ??!! Thanks ~~
